Product Description


The AD-1 is a fully seam taped, unlined, HT600 Denier Nylon three layer GORE-TEX® jeans-cut pant, with full length separating side zips. The outside zippers have full length inner and outer weather flaps to help the pants go on and off fast and keep rain and wind out.

Other details include: A diamond gusset in the crotch for greater sitting comfort; An inner gusset behind the front fly which improves water resistance; The knees have a greater bend around a larger radius (than the Darien pant knees), allowing more freedom of movement. The Scotchlight® reflective ankle tab loop strips are radial, for a natural and secure adjustment around the calf and lower leg. The front pockets have hook and loop secured cover flaps so items inside are secure. (And you won't lose your change or bike keys when the pants are laid over the back of a chair…). A vertical zippered cargo pocket is on top of the right thigh and a horizontal opening pocket to the top of the left thigh. Available in even waist sizes, 30–46 regular and long. An Aerostich Money Belt (#1854) is included with these pants. Black, Grey or Tan. Imported and Made in USA

If you are interested in suspenders (?) we recommend these #1815-1349. Several models and styles are available.

bummerReview by Jeff
I live in the Seattle area and after vacillating for 5 years i decide to jump in and try a one piece. Its always a gamble when buying gear through the mail and this was no exception. the first suit was too small so i couldn't really try it out so I sent it back. I thought about it awhile and ordered a second suit, It fit but after taking a few short rides realized it wouldnt work, just too bulky for me, so back it goes. I think maybe i will just get some new overpants, AD1s are backordered and they are making them stateside,I feel lucky. 2 weeks later they arrive,they look strong and of excellent quality, they fit and I throw the box away, that was dumb. One week later i am riding twenty minutes in a good rain and the crotch is wet. Bummer, its been six weeks and with this last return almost $100 in shipping. On tuesday Im going down to see Bill at Ride West, get some new riding gear and not look back. (Posted on 4/2/12)
warm and dryReview by hogcrazy
Great pants to keep you dry and warm. I have to say they could be a little warmer. But, its easy to throw on some long johns under your pants. For touring, there is noithing better for keeping you warm and dry. Xcountry several times now, and to have something that is easy to pack when not using is a big deal for us. Pants and jacket are like no other. (Posted on 2/21/12)

Excellent pocket design.
Definitely worth the money in my opinion. (Posted on 2/3/12)
First ImpressionReview by Lane
It was a great leap of faith for me to order these over the Internet without ever seeing them live, and being able to overcome my fear of them not fitting, or not what I hoped they were going to be.

My first thought was: "Quality" They are everything I wished for as far as looks and a critical eye going over their construction.

The second thought was: "Boy, I sure do hope these things fit..." Living outside the US, they cost me over $422 dollars with S/H, Import Duty etc., to get them, and the hassle and expense of trying to make a return would be insult to injury, if I was forced to do so, despite Aerostich's best intentions.

Living outside of America, you take a real gamble with this kinda stuff that all the "free shipping" and "simply return for refund or exchange" ease, unfortunately doesn't apply to you.

My main two purchase considerations, were to have FULLY side seperating leg zippers, and a built in GoreTex membrane, no hideous removable liner. I have a 20 year old pair of still perfectly functioning GoreTex rain pants with fully seperating side zippers, that made me truly appreciate those specs. That they are not Motorcycle specific pants, is their only drawback. The AD1's are their wonderfully augmented upgrade for me.

My first and only two rides so far, have been in the pouring rain, and I was actually surprised that I didn't get wet though...

There is a very iffy gap between the front of my jacket bottom and the top of the pants. I think if I was riding my other bike, (more upright) I would have gotten a soaked midriff. If the waist was only an inch or two taller, I would give them 20 out of 10 stars. As it is, they kinda feel like how those "Low Rider" jeans look. I sure wish the waist was higher!

This will force me to make a purchase of a different, longer cut jacket, before my next ride on my touring bike.

The last curious thing, there is no flap or zipper over the top of the rear pocket. I can picture this thing filling up with water, eventually. If I have to put my wallet (or whatever) in a ziploc bag, what's the point? I see no benefit to having a pocket exposed to the elements on a pair of rain pants. (This is also why I chose the AD1's over the Dariens, front pockets with open tops? Ahroo?)

I am sure hoping that the low waist thing isn't these pants fatal flaw, and I can somehow work around it. Aside from that, I am still glad that I bought them. Thanks, Aerostich! :) (Posted on 12/28/11)
So far, so good. Review by Michael
I have a 15 year old Roadcrafter. Love it but I purchased the AD1 pants along with the Darien to get more comfortable in colder, wetter weather. First couple weeks after I received it all we had was rain, rain, rain. It's great. No wet crotch. If I could ask for anything on this I would like the rise from crotch to waist another 1" or so. Reason? I wear heavy cotton pants and a thick belt to work and the belt line of the AD1 rides right over it. So I wind up taking my pants belt off til I get to work. OK, weird. I may not be the norm. But I like these. Riding position is moderate forward lean. (Posted on 12/25/11)
AD1 Review by Mickey
March 2011 i began research on what to buy as an over pant. I wanted something for cold weather and rain coverage. It had to be quick to put on and the ability to vent was crucial as I don't like to stop and change clothing unless i have to. after a month of every night on the computer I finally decided to fork out the extra cash for the ad1. I'm 6'2" with a 36 inch waist and 34" inseam. I ordered the 40 long. but had to send them back for 38 long. The adjustable knee pads are great. Normally I wear them over my regular riding pants when it's either cold or raining. They fold up nicely for storage and in the six months of wearing them they have never let any water through. The outside pockets are perfectly positioned. I can unzip while riding from the bottom or the top to get maximum air flow on my legs. I can see these being used for many seasons to come. thanks for the good work and special thanks go the people at Aerostich for the great turn around time in swapping the pants out.

AD1 reviewReview by Pete M
Earlier this spring I ordered a Darien jacket and pants. I am local enough that taking a day trip to Duluth wasn't a problem. Turns out the Darien pants would need to be customized to fit so I tried the AD1s on and wow, perfect.
So one season nearly down and they've been on multiple trips over thousands of miles of dirt and pavement. I've worn them in temps from the high 30s to over 100 and I absolutely love these pants. Totally waterproof and just right in every way. The only time I don't wear them is when I have my one-piece Roadcrafter on.
Kudos to Aerostich for putting out such a great product. I won't need another pair of riding pants until these are worn out which looks to be a long time.

New and ImprovedReview by Geezer
Early this spring, I thought my 5-year-old Darien pants had been stolen from my car. There seemed to be no other explanation, since I'd recently piled all of my gear in the car when I went to pick up my newest two-wheel acquisition. It turned out that my wife had bundled the pants up, hauled them into her sewing area for a minor repair, and forgot about them.

After searching the usual storage places a dozen times I gave up and visited my local motorcycle accessory store to buy a cheap replacement. I usually punish myself for being stupid (losing the pants, for example) by buying a crummier version of whatever I've lost. That was my theory this time, too. I looked at First Gear, Tourmaster, Icon, Alpinestars, Joe Rocket, and the rest of the usual suspects and learned that I am spoiled. The difference between the imitations and the real thing, Aerostich, is subtle but massive. For as little as $120 I could have had more pockets, a zip-out liner, an MP3 player pocket, and probably an insulated cup-holder with any of the above brands, but the zippers were lightweight, the material is flimsy, and the construction quality and workmanship is not even in the territory. So, off to Duluth we went for a "winter vacation" and a visit to the RiderWearHouse.

Looking for a deal, I found a pair of Roadcrafter pants that fit perfectly. I bought them, took them home, and discovered they were too perfect. I have a toad-like body and the Roadcrafter's attempt to make me look streamlined resulted in a fit around my thighs and calves that could be politely described as "snug." After a few hours around the house, I began to feel like Roddy McDowell in <i>Arnold</i>. When we found my old Darien pants, it was obvious how uncomfortable I'd be in the Roadcrafters. Taking advantage of Aerostich's money back offer, I traded the Roadcrafters for a pair of AD1 pants. (AD1 is for "Asian Darien 1," as the AD1 pants are the first US-designed, off-shore-manufactured Aerostich product.)

Like the lower priced competition, the AD1 pants are loaded with pockets (5), including a waterproof zippered "cargo pocket" and hook-and-loop secured cover flaps on all front pockets. No more lost billfold in the campground when I hang my riding pants out to dry. Unlike the competition, the HT600 denier nylon (up from the standard Darien's 500 Denier Cordura®) is tough and the oversized and durable zippers are classic Aerostich. The AD1 pants are a closer fit than my old Dariens, but the knee and crotch gusseting makes them at least as flexible right from the start.

One of the things I have always hated about most nylon motorcycle clothing is that god-awful flimsy perforated nylon inner lining that snags on boot heels and anything else with an edge and is usually torn to shreds after a few uses. The Aerostich gear is lined with smooth and durable GORE-TEX® nylon that holds up and is easy to get in and out of, regardless of the abuse I heap on it when I'm tired, hurting, and grumpy after a day's ride or a bad night's sleep.&nbsp;GORE-TEX® works, by the way. I have ridden in downpours in my Darien gear and the few leaks I discovered in my old Dariens are plugged in the AD1s; the gusset behind the fly being the best idea since the pocket knife.

The single most valuable improvement I can suggest for the AD1's would be double-height hook pads for the knee pad mounting. The current pad position works for some people and, according to the company's reviews page, works badly for a few of us. I realize that my troll-dimensioned body represents a one-man counterargument for Intelligent Design, but there appear to be a few of us out there based on the company's website reviews. I'm cautious about the supplied money belt, too. I've had an Eagle Creek (from REI) money belt that uses the same nylon buckle and it has been fragile, to put it mildly. The Darien belt's side-release buckle has been bulletproof for 60k miles and if it ain't broke, I say "keep it."

Many things farmed to Asia are well-designed but suffer workmanship flaws. My AD1 pants were no exception. The fly zipper began to disintegrate at the bottom because the stitch missed the zipper tape. Not something that would pass any part of the Made in USA Aerostich process, but something Aerostich will have to inspect for with the Asian product. Aerostich repaired the broken zipper for free and got the pants back to me in record time.

After three months of cold weather riding, a long hot summer, and two options for riding pants, I found myself almost always opting for the AD1's. The pocket security is a big deal; having lost keys, a billfold, earplugs, a retirement plan worth of spare change, receipts, and a sense of personal security to the slippery front and rear pockets of my old Darien pants. The crotch and knee gusseting makes the stretch on to my bikes easier. I haven't used the extra pockets much, but it's nice to have them. The AD1's are somehow more comfortable than my well-broken-in Darien pants that were specially tailored to my troll dimensions. It could be that familiarity is simply breeding contempt, but I'm feeling the beginning of a new long-term relationship.

Excellent PantsReview by Grahame
Received these pants in good time considering I'm in Australia. Excellent quality in materials and workmanship. Fit is perfect with extra long legs that are at proper length when riding. Used for cold weather riding and thye're exactly right with jeans beneath. Have yet to test them in the rain - I expect they'll work perfectly well. I'm very pleased with this purchase.

Best Pants everReview by Girseach
I mistakenly ordered the AD1 pants instead of the Dariens and it has been the best mistake I've ever made. My husband has the Dariens and the AD1 is far superior. I've ridden over 13,000 miles in these pants. Yes, they are a bit stiff at first but after that I could live in them--and did for three weeks in Alaska and the Yukon. I love the pockets on the front legs. I found them to be very handy for stashing my earplugs when we got off the bikes for fuel. Durable, rugged and attractive. What more could you want from a pant?

Gear: Fashion and Style vs. Equipment

There’s a lot of ‘noise’ in the rider-gear market space the Aerostich Darien jacket occupies, about how ‘new and improved’ similar jackets are. Other companies making these kinds of jackets restyle them and revise them every year or two, telling riders that if three zippers is good, six or seven zippers is better.

What all the ‘noise’ amounts to is fashion and style being presented in the guise of technology which supposedly is rapidly ever-advancing in this area. Except armored waterproof textile jackets are not the same kind of technology as computers, or even motorcycles. Seven zippers are not better than three, if only three are functionally needed. What counts is ease of use, durability, fit and function. The pioneering of this type of gear was done by us twenty and thirty years ago. (Combining lightweight breathable-waterproof highly abrasion-resistant synthetic fabrics, seam-sealing, ergonomically more useful vents and pockets, reflective materials and energy-absorbing foams and plastics.)

Since then, just like added decorative stitching on branded ‘designer’ jeans turns a pair of useful, comfortable and durable work pants like Levi’s 501’s into a fashion, all the noise about new tech in jackets like the Darien is mostly fashion BS masquerading as technological improvements. It’s not real.

Classic black leather ‘zipper’ biker jackets have been popular world-wide for many decades. There are versions at many price points and in some circles this jacket has become a fashion cliché having little to do with actually riding a motorcycle. But for many riders it remains a great equipment choice that has changed only very slightly over the years — because it works so well. You’ll find the original versions of these jackets at Langlitz, Shott and several other pioneering leather companies. Similarly, you’ll find the original British waxed cotton Belstaff and Barbour rider’s jackets and pants still being produced in their original patterns because they remain excellent functional rider’s gear.

The ‘latest-greatest’ is usually more style and fashion based, and original equipment is nearly always more utility-tool based. It does not change from year to year any more than Levi’s 501’s. Many riders are unlikely to admit they are buying ever-changing fashion and style when they believe they are getting some kind of improved technology, but that is a truth. None of the regularly restyled ‘teched-out’ sportswear for riders comes in as many closely-spaced sizes as the Darien does, and none is as functional and equipment-y as a Darien.

The Aerostich Darien is the original advanced technology breathable-waterproof impact-armored synthetic (nylon) textile rider’s gear, and just like the above-mentioned other examples of specialized rider’s clothing, it is similarly more equipment than fashion. For historical reasons.

Dariens are available ‘off-the-rack’ in eleven closely-spaced graded sizes and six colors. Complete repair service and several optional fit alterations insure years of superior service.

"The Darien and AD1 pants fit a little different…The Darien's fit like khaki 'Docker'-type chinos and dress pants. They have a straight waistband and a higher rise than jeans. The AD1's have a lower rise and a slightly conical waistband that is angled a bit lower in front. So these fit more like old-school denim jeans. I slightly prefer the AD1's fit."
