Product Description


The fastest, most comfortable, versatile and easy to way to carry stuff on a motorcycle, scooter or bicycle. Triangular in cross-section, messenger bags wrap around your back and stay in position when riding. The original ‘Courier’ size holds a small briefcase, a few magazines and some files…plus a tablet and notebook computer with room to spare. It is the most versatile and best selling size.

All are constructed of 1000D PU-backed Cordura nylon, with a seamless bottom for maximum strength and durability. All also feature a bright yellow reinforced PVC waterproof inner lining. Also inside is a usefully-sized organizer pocket (two on the Parcel size) and ‘clip-on’ key loop.

After long use they’ll develop an ‘experienced’ patina that reflects your individual patterns of use and wear. The 2" military-spec nylon shoulder strap adjusts quickly and easily via a cam lock buckle for a secure, comfortable fit. For heavy-load all-day comfort, there is an oversize, removable, load-spreading shoulder pad with a grippy Ultrasude surface (it’s optional for the Letter size).

The flap closes with a wide strip of hook and loop as well as adjustable side-release buckles to accommodate oversized loads. There's also a useful carrying handle on the top center. Visibility is assured with a wide strip of 3M Scotchlite™ reflective running across the flap.

These bags are as simple to put on as a guitar, and easier to learn. Red, black, grey, hi-viz lime yellow, or blue (or limited edition pink in letter, dispatch, and courier sizes only).

Four sizes: Letter (9"×3.75"×9"/12"), Dispatch (12"×7"×12"/18"), Courier (12"×7"×18"/23"), Parcel (14"×9"×18"/26"). Made in USA

Aerostich qualityReview by Stephen
I was looking for something to replace the old gym bag I would use to take my stuff back and forth to my teaching job. Way better than having to fasten bags to my Blackbird and, after having been knocked off my bike on the freeway a couple of months ago, I appreciate the big reflective stripe. Very comfortable, stays in place and typical Aerostich quality. I expect this bag to last many thousands of miles. (Posted on 10/9/16)
Love This BagReview by Melanie
Bought the Courier bag (pink!) last year. I most often place it inside the side case on my Vstrom. I like it better than the side-case manufacturer's dry-bag. I can pack a weekend's worth of stuff, and be able to just pluck it out of the side-case, sling it over my shoulder and have my hands free for helmet or whatever as I head to the hotel check-in desk and thence to the elevator. Plus, if I collect stuff during a trip, that can go in the side-case, the Courier bag comes out and can be strapped to the rear seat or slung over the shoulder with no worries about weather. Maximum versatility! And pink rocks! (Posted on 6/24/15)
Bitchin BagReview by enduroed
Bought a Messenger bag on Ebay, and while nice it was too small for my Dell m6800. I now use it for a gym bag.

I then bought a Courier bag and a laptop sleeve from Aerostich. I live in Central Florida, own a small machine shop, and teach at a local tech college. I commute on my K1300S and always carry my computer and books in the bag. It rains in Florida, often quite hard. I've been through 5 torrential downpours and numerous rainstorms and all I can say is that I do not fear the rain getting thru to my computer, or any books I carry. I purchased the stabilizer strap and thru almost 40 years of riding bikes can honestly say this is the best gear bag I've ever owned. I sincerely believe in American craftsmanship and am proud to tell people this is a top tier example of that craftsmanship. The bag is comfortable, WATERPROOF, very sturdy, and with the reflective material my wife says is very visible at night.

Thank-you Aerostich for such a good product. As my gear purchases warrant, I will always stop by your site first.

Recently had a spirited ride alongside a Testarossa, spanked him and did not even feel the bag. 180+ with the bag and it did not budge.

Ten years of daily use and going strongReview by Alan
I'm a high school teacher and have used messenger style bags for my whole career thus far. Most of the fashionable ones I've tried lasted one to three years of daily use before disintegrating. Also, they proved to be irritating, requiring an intestinal jumble of bungees to hold them onto my seat while motocommuting. My 'Stich Courier Bag is superior in every way. It holds far more books, papers, etc. than "stylish" bags, and even swallows a laptop. It is easy to sling over my shoulder carry on and off the bike. After at least ten year of use, it shows very little wear other than a proud patina of road grunge. The authoritative "riiiippppppp" of the Velcro flap signal to all that class has begun. Parents of students who ride nod approvingly during conferences. . . (Posted on 7/19/14)
Huge!Review by John
I ordered the Courier bag for my daughter to use as a book/carry whatever bag for school.
The Courier bag is way huge! I could pack for a whole weekend in it. So I returned it (paying for shipping both ways, ouch) and downsized to the Dispatch bag, in pink (of course) Perfect fit. Well made, and should last her a long time!
With enough room for all her books, lunch, plus a raincoat or whatever she might need. (Posted on 2/27/14)
I Just Discovered One Huge Advantage Over BackpacksReview by Ted
Alright. I just commuted back home and pulled out my laptop to write this.

Today I made an unscheduled stop to do a little Christmas shopping. No worries about parking, I'm on the bike during the crowded holiday season here in Socal.

My Vstrom's two side cases already had work stuff in them & the topcase had this bag in it with my change of clothes for work.

This is important later.

So I walk into the store "just to look" and roll out with three boxes. I have a problem now though. Lot of stuff to carry on the bike. Courier bag comes out of the Givi E55, two boxes go back in the Givi.

3rd box still an issue.

No problem, I use the bungee net I ordered from Aerostich at max stretch factor to get the other box on the pillion seat. All cases are full. Pillion seat is full. Put the Courier bag over my shoulder. Stuff is handled.

Ok, cool.

Sit on the bike, and realize the Courier bag can't go to it's natural resting position with one corner resting on the pillion seat. So I move the bag forward and it then rests sorta on my side, but actually on my "hip crease".

Not all the way on my thigh or in front of my chest, and not all the way to the side with all the weight on one shoulder just dangling on the side of the bike.

In between the two positions.

To finish up, if I had a backpack like a Kriega or something, I wouldn't of been able to get all this stuff home-the pack would of stuck out into the pillion seat with the huge box strapped to it and I would of been not able to fit on the bike.

All I had to do in this case is slide the Courier bag forward a little bit, and I rode 15 miles in total comfort with no shoulder strain and zero impact on riding or controlling the bike.

Everything made it home in one go. Saved time and saved gas all while doing a task that I normally dislike.

Motorcycles are awesome. Use one as a car replacement and you won't go back. Challenge yourself to only use your bike for six months. I did and haven't looked back.

Aerostich products make it easier. Like this bag. (Posted on 12/12/13)
Serious bang for the buckReview by SteveW
For about a month now I have been using an Aerostich Courier bag when commuting to work on my 2007 Suzuki V-Strom 650 and my 2012 Suzuki GSX-R750. As you can imagine, the body position is rather different between these two bikes. The V-Strom has an upright, neutral position and the Gixxer has me leaning forward with my elbows practically touching my knees.

I use the Courier bag to carry my lunch, an iPad, an external hard drive, and a few other miscellaneous items. The total weight is around six pounds.

The bag itself is one large compartment. I purchased the additional pocket organizer that attaches to the inside panel (that presses against my back) with hook-and-loop fasteners. In this I store pens, business cards, a small notebook, and a few other small miscellaneous items.

I switched from using a Targus backpack with traditional shoulder straps and several external pockets, and so far I think I like the one big compartment of the Courier bag much better. It's faster to get stuff in and out of the courier bag, and of course it's easier to see in a single glance what is inside.

My biggest concern was switching from shoulder straps (plural) to a singular over-the-shoulder strap. Once the bag is slung over my head to the opposite shoulder, it presses against the flat of my back and I don't notice it anymore after I get on the bike. Even when leaning forward on my Gixxer, the courier bag is comfortable and stable.

The hook-and-loop panel holding the main flap down is very wide and opening it can be rather loud.

I commuted to work through some serious rain the other day on my V-Strom while wearing my Aerostich Courier bag slung over my Roadcrafter one-piece suit. The bag remained stable and the contents were kept completely dry despite the heavy precipitation. I'm sold on the quality of this bag and wish I had purchased it long ago.

The craftsmanship of this bag is outstanding, just like that of my Darien jacket and Roadcrafter one-piece suit. The materials are solid and I can tell this bag is going to last me a very long time. Considering the very low price, I think it is an outstanding value. (Posted on 11/7/13)
Go-to courier bagReview by Keith S.
The bag due to the quality of its material is very stiff and unyielding and will require some break in time.(this is a good thing) It is cavernous and seems somehow magical in the items it seems to be able to carry, it just keeps expanding somehow. Yet when you only have a few things in it, it does not wear like a sea bag that is empty. It wears small.
The organizer is very useful especially the back zippered pocket which will hold a couple magazines. It could not have been easier to install with the Velcro already in place.
The stabilizer was tested on my BMW R1150GS at 100mph and it did not flop around or move around even though it was nearly empty (BTW, I am 5'8” tall, 185lbs with a normal build). My BMW courier bag would be airborne and become very annoying in any cross wind. In its defense I did not have the optional stabilizer strap.
Also, the strap pad is awesome! With about 30 lbs of weight in the bag it was not digging into my shoulder at all when I was carrying it around, off the bike, with just a T-shirt on. Amazing!
The con, and it is the only con that I have, no outside pocket. The BMW bag has a waterproof zippered pocket on the flap that can hold small items, I carry a small Bible in it so it would be accessible in a moments notice. Very convenient. With your bag, two clips and all that Velcro, (how many Velcro trees were killed in the making of this bag?) it is annoying.
In short, anytime I ride my bike, I grab your bag. The hi-viz yellow and the reflective material and the pad, oh the pad, I will use nothing else. I have yet to test it in the rain and don't even know if you claim that it is waterproof (?).
It is an outside waterproof pocket away from being sheer courier bag nirvana. If you come out with an bag with an outside pocket, you better take trade ins or I will picket! (Posted on 7/12/13)
If Chuck Norris needed a bag, he would buy this one!!!Review by Chris B.
Well made bag. It contains my earthquake bug-out gear and lives near my front door. This is the bag you want when the stuff hits the fan. I can live for two weeks with the contents inside this bag.

"Hey Chris, I thought this was a moto bag review?!?" Hey - shut up. Get on your bike and ride. This bag shifts all over the place when I ride and I found a better use for it. Stop reading this and buy it. Get the yellow one. (Posted on 7/4/13)
Still going...Review by Adam
After about 15 years I cracked one of the small plastic buckles on this bag. Today it goes back to Aersotich for repair. The buckle breaking was totally my fault, and it's awesome that I can get it repaired. This back has been through the ringer over and over again and still looks and functions great. This is awesome compared to all other choices. (Posted on 4/30/13)
courier bagReview by james
the bag is a good one. the only 2 faults that i find are the velcro is way overkill. it takes some force to get the lid open. and when i am in a meeting and have to open the bag the noise is really distracting.

the other thing is the accessory pouch as an additional cost. a simpler pouch should be included within the price, and the design could be simplified. this business of accessories as an additional cost is a marketing tool to make additional more profit on the product. just keep it simple, include the necessary pouch and keep the price down.

thanks for this opportunity to respond.

SuperbReview by Conchscooter
The courier bag works exactly as advertised. It's more comfortable than a backpack tossed over one shoulder, and worn around the neck (minus the padding) it is as comfortable as the load allows. Unlike a backpack you can look for stuff inside the bag if riding and are stopped at, say, a light. The bag is versatile and indispensable. The details prove once again that Aerostich use what they sell. (Posted on 6/7/12)
Need a bomb-proof bag?Review by Mike.B
If you do, get a Courier bag. Mine has hauled college books, a laptop, enough supplies for a small office, a water bottle, and my lunch for the past year. Yes, it's snug, but it all fits. I'm in the Northwet, and the only time water has entered the yellow cavern of this bag was when my old water bottle leaked. Winter storms, on and off the bike, failed to put more than two drops inside it. The corners are just starting to get fuzzy, and it has some stains, but not one thread has popped even when the weight exceeded 40 lbs. Campus is big, and I do a lot of walking, so I needed a bag that could survive when one term savaged a Jansport backpack.

About the only downside to hauling so much around is, the items tend to get their share of scars. Softcover books have their spines and corners worn, spiral-bounds tend to get hammered hard. But then I'm not nice with the bag. It gets dropped, slid, shoved around and occasionally tossed. Yet this bag doesn't quit, doesn't leak, doesn't do anything except take my stuff where it needs to go. (Posted on 5/9/12)
a bag's bagReview by Greasy
this is the bag that your Chrome or Timbuktu bag wants to be when it grows up. I was super close to getting the chrome one because of the quick release on the strap. decided to go with aerostich however as it is moto specific and Aerostich has never let me down. Besides every other trendy hip-guy on the street has one of the other two. I am so glad I went with the 'stich. I use it for school, work and the gym. all at the same time. it will hold my 17" laptop, in it's padded case, with room for books and work clothes! it conforms to you when it is empty or close to, making it very comfortable at all times. I have found that it works better over the left shoulder, that way the release for the strap is on your right and easy to reach. you can tighten or loosen the bag without spinning it around. I realized the other bags seat-belt quick release buckle was unnecessary and would prob create pressure points, dig into chest, interfere with zipper etc. with the stich bag you can have it cinched up tight, but when you want to take it off with a heavy load you release the clamp and pull the shoulder strap up to pass over your head without actually lifting the whole bag. or just release and let it go to the floor around you, step out. the point is it's perfect the way it is and doesn't need a quick release. yes there are 2 places where water could potentially get in at the top, but if you are careful to close it evenly and tightly when it rains there is no way water will get in. I got the grey one and love the color,look of it. very nice, subtle styling, obviously well built with the best materials. the only thing I didn't like was the strap pad. it didn't work well with my shoulder armor. I think given time it would have conformed and gotten comfy, but I bought a maxpedition one to replace it and found that it works very well. I also got a "molle" style shotgun shell soft-pack from ebay that velcros onto the strap and is perfect for carrying cell phone or sunglasses, it has velcro on the front for sticking a patch on, I use it to temporarilly attach my gloves to when I get off or put on helmet, etc. it holds them for you! I am super happy with the comfort, convenience, etc. well done Aerostich! (Posted on 2/23/12)
My second bagReview by Allen
I purchased a courier bag almost 15 years ago. I have been using this bag every day for the last few years to carry my laptop and general "stuff" It still looks great. I purchase a hi Vis replacement so that I could send in my original for some sewing repairs. There is not a better courier bag on the market. Some of my friend that ride bicycles have switched to this bag, even though it is heavier than the bicycle specific bags, because of the superior construction. (Posted on 7/20/11)
looks great and works betterReview by William
Purchased this bag mainly as a gym bag. With the organizer pockets I have everything where it should be. Works great as an overnight bag and we'll use it as a carry on when flying. Another great product from Aerostitch. (Posted on 11/4/10)
Look out theres a monster comingReview by Timbob
The dispatch bag I've used for 11 years and 50,000 miles has been replaced by a clean, bright, odor-free courier bag. The dispatch was great- unobtrusive, comfortable, and big enough for 90% of the loads I wanted to carry. I was even able to strap down a brand new full-length lacrosse stick using only the QR straps attached to the bag. The dispatch has been relegated to only bicycle duty, as several years of sweaty bicycle use has lent it a delicate bouquet that remains even after a good hosedown. The black fabric is faded, the reflective strip is...disreputable looking, but the velcro, seams and strap all remain strong and intact. The current overall appearance of the bag, to me, reminds me of the miles I've ridden, the lessons I've been taught, and how something old and obviously well-made and well-used will always be cooler than some brand new shiny thing that starts to deteriorate in a month.
The courier bag- bright blue, way too big for what I need, but still mighty handy. My complaint is the size, or rather the attributes that the size of the bag brings to its construction. The main culprit is the velcro- even when the bag is fully loaded the velcro is so strong that two hands are needed to open the flap- one hand to pull the flap, one hand to hold the bag down, as the velcro holds tenaciously and lifts the bag rather than separating. I have NEVER had a problem with the flap coming open on either bag. Perhaps more judicious use of velcro is in order?
The dispatch bag was small enough that it didn't fold or flop around like the courier bag does- it can be a struggle to get into the courier while riding, just because the bag contorts and bends funny when its wrapped around ones back. I have no solution for this, other than going back to a dispatch-sized bag.
Otherwise, magnificent construction and durability. (Posted on 6/25/10)
Platonic Ideal of Courier BagsReview by Lorin Rivers
There are many, many things to praise about this bag. It's simple, functional, and stylish. The bright yellow interior makes it much easier to find stuff in it. Plus, you can get one of “their” courier bags anywhere. You can only get this one from Riders Warehouse. (Posted on 6/2/10)
Laptop friendly and very stable on sportsbikeReview by Tim
Needed a solution for commuting and business trips - a mobile office.... And the occasional large item/purchase (shoe box+). Exceeds expectations. Very stable despite hanging off through esses on a ZX10r. Looks like it will leak at the flap top and some other bag designs fold this over e.g. North Face to avoid likelihood, but no water in so far. Good kit. (Posted on 1/26/10)
Useful, comfortable, safe. Awesome piece of gear. Review by Bill
I have only been riding for about 11 months but I can honestly say that I think this is tied as the best investment I have made when it comes to gear. (a comfy helmet for my over-sized melon, being the other) I purchased the hi-viz version only a month after I starting riding and, every rider that I have spoken to about the bag, says they can see me coming in traffic. And while I do not ride to necessarily show off my gear, if the hi-viz bag or its shoulder pad wake up the phone-toting left-turning SUV driver to my presense, I am all for it. I have carried many things in this bag and most, if not all, of the time I never notice that is even there. As of today, I never leave home on the bike without this bag. Thanks, Aerostich, for an awesome product! (Posted on 8/13/09)

Our favorite Messenger bag, too...

A Mr. Subjective History on Aerostich Messenger Bags

The Aerostich messenger bags are one of my most-favorite Aerostich products. We have been making them for over twenty five years, and they differ substantially from all of the other kinds of similar bags. Essentially, ours are a lot heavier-duty...

I like messenger bags so much because they are so easy to use for urban and utility motorcycle riding. They go on-and-off quick and are versatile. One of these bags hangs empty, near my riding gear so I can grab it whenever the destination involves picking up something, or when I need to carry something fast, without using bungees. Many of our customers use them for their routine daily commute, too. Messenger bags are a key technology for motorcycling personal mobility…An invaluable tool.

Our bags were the first ones ever made of a synthetic material (Cordura Nylon and reinforced vinyl). When we began, there were two or three others made of coarse canvas. Ours was also the first courier bag to employ Velcro (hook&loop) anywhere, and to have any 3M Scotchlight reflective, and to have a handle on the flap, and to use ITW Fastex side-release buckles. What was available elsewhere was crude -- bags made in small numbers in cities like New York, mainly for working bicycle couriers.

About a year after introducing Aerostich Messenger Bags, I remember being at the Motorcycle Dealernews trade show standing before Motorcyclist Magazine Editor-in-Chief Mitch Boehm, and several other editors, all of us in a small conference room in one of the hotels there,…giving a presentation. And the internet was years in the future still.

“The daypack is dead!” I began, trying to sound as declarative as possible. “The era of the messenger bag is now beginning.” I then explained why these still largely-unknown types of bags were so great for motorcyclists. And why they’d rule in the future. And why the Aerostich courier bags were made they way they were. It felt as though we were pioneering something entirely new.

A few years after we started making Messenger bags, other companies like Timbuktu (and many others) were started, and they made lighter-weight versions of messenger bags a common college bookstore commodity. About a decade later Chrome -- another company – added some contemporary hipster style and an automobile seat-belt buckle to the shoulder strap. And today there are countless other varieties from dozens of companies.

But the Aerostich messenger bag line (by size: 'letter', 'dispatch', 'courier', and 'parcel') remains the real-deal and ‘the original’ in terms of function, utility and durability. They are still the very best of this kind of bag available anywhere.

Recently we introduced a wax cotton variation in several colors. And a few years ago we added pink to the available colors of the Cordura models, and developed an optional internal organizer pocket system (available for the three larger sized bags).

Many specific patterning and stitching details set ours apart from the others. (One example - the lid-edge is turned and then hand topstitched. This is how a button-down shirt collar is made. It's neater, stronger and more expensive to do it this way. It makes a better flap. Almost everyone else's bags use cheaper machine-bound edging.)

Lastly, a special feature of our bags that I think is pretty cool is that for over fifteen years Aerostich messenger bags have been made by one individual here at Aerostich. And this person is a life-long motorcycle rider. During the years he's been employed here he's owned three or four different bikes. Recently he’s been riding a black Kawasaki Concourse. And he’s already been to North Carolina to visit his daughter and grandchildren on it a few times.

When you buy an Aerostich messenger bag, you are getting a hand-made classic American product, and an incredibly tough, practical, good bag.
