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.”

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.

I still have the courier bag I bought in 1992 as I started Law School in Memphis. It’s still in my office. It doesn’t get used as much now, as I have a larger bag I got a few years ago, and which I used today on my walk to court with all my files for some 20+ cases. Love that dang bag. Works everywhere, and when you don’t want it around your body on the bike, it still straps on easily to the back or works as a larger packing cube inside my side cases. Just the most useful bag to own.

I, in the eightes and nineties was a genuine bicycle messenger using likely two if not all three of the bags you mentioned. Zo, Timbuk2 and DeMartini, the DeMartini was the original, black canves duck, yellow inside metal strap buckles. Bomb proof. Early onshore timbuk2 were good, they got cheap and less function focused after they got bought and sold on the outdoor gear circuit. We looked at your early bags back around 1993 when the strap was still floppy seat belt webbing. But you had some solid ideas on how a bag should be made and function. I picked up a little letter bag in waxed canvas about maybe 10 years ago, in brown with reflective delete, it was my Every day carry mini brief case for about four years until it just wore out, i replaced it with another one, retiring that one while it was still mostly functional. Great solid bag, with ideas that make sense like the protection on the corners and the handle on top.while my now limited budget have precluded me from getting another one, the one i do have still gets random compliments from strangers, this is something i have never have happen with any other bag i have ever carried.

Hi Mark, in response to your question, the bags have no internal structural divider, except one wallet/checkbook/smartphone sized interior pocket. We will have more photos added to the website soon. Thanks for reading!

For the career welder / fabricators out there, I got the biggest one, the “Parcel Bag”. The width fits any welding hood easily, even a Speedglas with PAPR belt. Plus fits the other standard stuff like an FR jacket or leathers, gloves, water bottle, couple of hand tools, etc. There’s an add-on interior pouch when ordering and it’s good for little items like earplug packs, alcohol or respirator wipes, cell phone, and a notebook for weld settings. The outer flap’s Velcro strip is super wide which is nice for if the bag is super stuffed, or almost empty. The simplicity of build makes it easy to get in and out of throughout the day… just open the flap and everything is within sight and reach. The bag is built tough, very high quality, and the shoulder pad is included and comfortable. Last but not least, MADE IN THE USA. I care about that. I make parts here too, and if my purchase can support a neighbor also making a living with their craft… I’m all in.

I like using my motorcycle to run errands, and until recently have had machines with hard side cases. My latest motorcycle is a Honda 300 Rally, because I had grown tired of bikes weighing 500+ pounds and wanted to do more gravel road riding. Thinking of ways to carry groceries, beer and hardware store purchases, I remembered your messenger bags and found a used Courier model. It won’t swallow as much as a set of aluminum side cases, but it holds enough for most trips to the store and is so convenient to use. Thanks for making a such a well-thought-out and durable product!
