And a Little History Nonsense
“What I always like about Aerostich gear (and the messenger bags…) is the little things like the buckles, shoulder pad, etc. While other gear makers use technical materials that stretch or have other comfort enhancing features, Aerostich's KISS-principled equipment that still answers questions of function in practical fashion seems, to me, to be a great long-term solution.” - Zack Kurylyk, by email June 25, 2026
Thanks Zack. These messenger bags (and other similar bags made by others) are one of the most underrated and subversive products in all of motorcycling. They make it far easier to load and carry things when short-hop urban riding (commuting, errands, etc) and this greatly increases the likelihood of any rider choosing their motorcycle for utility transportation, instead of driving their car. If that is not what a subversive product is, I don’t know what one might possibly be. The larger mainstream world wants everyone to consume and use automobiles…Safe, comfortable, orderly, calming and uh, for the most part, overly boring compared to riding a bicycle or motorcycle. (Despite all that I enjoy using my car whenever I must use a car for some reason. This usually means driving only once every few weeks during the summer. Which, combined with aging, has turned me into a lousy driver.)
Some have noted Aerostich messenger bags are a copy of pioneering messenger bags. This is partly so, but ‘Inspired-by” is a more accurate description. When we were developing ours several fairly good messenger bags were already being made, but they all were crude and intended mainly for commercial courier use. Before the internet and email, professional riders used either bicycles or motorcycles to quickly deliver legal documents (and similar) across urban areas quickly.
What is true about the development of Aerostich’s range of messenger bags is this: The first two messenger bag sizes (the Courier and Dispatch models) were created and introduced in 1988 or 89. Our first step involved sourcing examples of the two or three already-existing commercial-use messenger bags so we could study and experience using them. One was made in NYC by 'Manhattan Portage’, and again this bag was mostly sold to professional bike and MC couriers working there. Side note: they were made in NYC until 2002, then manufacturing was outsourced to somewhere in Asia. They are still in business today. Another messenger bag was made by a company in Portland or Seattle, and I think a third one came from some company in San Francisco. After trying each for a few days I thought we could improve on all of them, so our version included dozens of refinements and improvements. Some changes were more important than others.
For example, I did like the approximately triangular shape of the ‘Manhattan Portage’ messenger bag but that was about the only element. This bag’s overall detailing, and how the pieces were cut and arranged to be put together, and all the straps and hardware, were different from what I wanted.
Every product is made to a recipe. Messenger bags are no exception. But note that a blueberry pie is not a copy of an apple pie simply because both pies come out of a circular pie pan. Same with a McDonald's hamburger vs. all the other fast food franchise burgers. Each business’s recipe is usually unique and different. The recipe for Coke and Pepsi is unique to each, and each recipe has its devoted fans.
Similarly, Aerostich messenger bags are different than all other messenger bags, despite and roughly similar shape to several of them. Many messenger bags are approximately similar in shape, but the details are all different and add up to completely different products. Aerostich messenger bags are generally more heavily constructed and stitched than most others, especially the popular lighter weight bags from companies like Timbuktu and Patagonia. Ours are also very simple compared to many, but arguably a lot more versatile and durable. Ours have more useful and unique details like the tubular webbing grab handle centered at the top of the lid, and a large area of Velcro loop for the flap to attach to, even if the bag is over-filled and the lid cannot be fully closed. There are dozens of other examples of detail differences which make the Aerostich messenger bag recipe unique, and, at least to me, superior.
I don’t specifically remember if any of the early messenger bags we’d purchased were made of Cordura nylon or if any had plastic (Delrin) buckles or hardware, or a nylon seat-belt webbing shoulder strap, but maybe one of them could have had such features (?). I do clearly remember at least two of them being made of heavy unwaxed cotton canvas and having aluminum or steel shoulder strap length adjusters. One had two short strips of reflective material clipped loosely to the top flap just dangling there. One of those bags was unlined. Another had a thin 1” wide strip of hook and loop for the flap which required careful alignment every time the flap was closed. Another had a yellow nylon fabric lining. Several had ‘binding’ around the edges of the flap. I hate binding and like edge-stitching, which our bags have. None had that carrying handle I wanted on the flap. None had any reflective sewn directly onto the flap or anywhere else. None had an oversize shoulder pad on an easily adjustable shoulder strap. None seemed built as ‘heavy duty’ or were as carefully-detailed as what I wanted Aerostich messenger bags to be. Blah, blah, blah.
I obsessively wanted a more durable, more well-made and more well-detailed messenger bag than anything else out there, and that’s what we ended up with. Soon, I came to know several of the owner-operators of professional motorcycle courier businesses. One was a guy who owned and ran a successful messenger and courier company in San Francisco. This was decades before DoorDash and the rest of the internet. More blah, blah, blah. Sorry.
The last part of this is about how the bags we make today are not static, and not exactly the same as the very first ones. Whenever we can figure out how to improve them, we do. For example, the reflectives and hook-and-loop used in these bags have been improved by their manufacturers several times, and we now use the current versions of both. And the oversized shoulder pads now hold up a lot better because we use a better foam for this application. There have been improvements in the patterns and stitching details also. These bags are even better now than they were. I’m sure incremental improvements will continue, but the core values embodied in each bag will always remain: Durability, ease-of-use, and functionality. - Mr. Subjective, June 2025
PS – These bags come with lots of old stories. I remember one time someone filled one with loose ice and bottles of beer and were everyone’s hero on a hot campout. Another time, it was campfire wood. The year we were introducing them, I’d brought a duffel bag full of them to the old Cincinnati Motorcycle Dealernews trade show and had reserved a time for a presentation to the editors of Motorcyclist magazine. That year they’d booked a private hotel conference room so companies like Aerostich could present their products to their editors away from the chaos of the show. At the appointed time I walked into that room and found the publisher of Motorcyclist, Dick Lague, the editor-in-chief, Art Friedman, and several other editors including Mitch Boehm, Dexter Ford, Tim Carrithers, Marcie Baritz and Nick Ienatsch. All were sitting around this big conference table in semi-reclining comfortable chairs. I set the overstuffed duffel bag on the floor, zipped it open and covered the table with an array of Aerostich messenger bags in many colors. Then I took a deep breath and in an oratorical voice declared: “The book pack is dead! The day pack is dead! This is a better way to carry stuff on a motorcycle!” Then I went on to explain the many features and advantages of messenger bags: Faster to put on than using bungees to hold something to a rack. More reliable than bungees and a rack. It took maybe five minutes of that oratory to explain the ‘why’ of the various sizes and all their technical details. I don’t remember any questions, so at the end I thanked them, picked up the now-empty duffel bag from the floor, and with a sigh of relief left the room exhausted by the stress of doing this presentation. A few months later, there were product reviews published about those bags, and they also started showing up in random Motorcyclist magazine editorial photos. Why do I remember this moment so well forty years later? Adrenaline, friends. Adrenaline is a memory fixative, and I was scared as heck having to give a product presentation to those moto-journalist experts. What did know about motorcycling compared to those editors? Today, I look back and wonder if any of them (all except Mitch, now long retired) still have and use one of those bags.
