Original text from 2012, the listing above is updated regularly: The list of lightweight bag makers is growing. Inspired by their own lightweight bicycle travels and the growing bikepacking and endurance racing scene, these craftsman are making ultralight bags for rack-lite or rackless touring. Lael recently picked up an Oveja Negra front accessory bag called the “Lunch Box” at SubCulture Cyclery in Salida, CO. The bag is made locally in Leadville by a promising upstart comprised of a seamstress with a riding habit and a rider with a sewing itch. Constructed of the now standard Dimension-Polyant VX-series sailcloth, the bag holds a paperback Gogol novel as well as a windbreaker and small personal items for easy access during the day. Made in Durango, the Bedrock “Chinle compression panel” pictured below was spotted on the Colorado Trail. As every town should have a brewer and baker, a framebuilder and a bag maker would also populate my ideal town.

Excellent post! We are linking to this great article on ouur site.
Keeep up the great writing.
Hey Nicolas! Knowing your fetish for canvas bike bags, I thought you might like to add Frost River to your list: https://www.frostriver.com/product-category/bike-bags/ + https://www.frostriver.com/our-store-workshop/about/ . Tough stuff — with a long tradition on canoe waters — and Made in the USA (Duluth MN)! Waxed canvas, leather, rivets and brass buckles and D-rings…what’s not to like? Search Google (Images) using the terms Frost River Bags Cycling for some enticing pics of canvas-geared bikepacking rigs.
Wayne, Thanks for sharing.
I like waxed canvas and I love the Carradice Camper. I do like the Frost River bags and other similar canvas bags from the north country, but I have to admit that most of their bicycle products don’t seem to improve upon anything, except to cater to those with canvas fetishes (of which I am not one). I think their modern style seatpack could work, but not with the leather straps and hardware as shown. I’d consider it with durable nylon webbing and plastic or metal sliders. I’ve replaced much of the leather straps on my Carradice with nylon over time.
So, I haven’t discounted waxed canvas, but the design of the bag is essential to bikepacking synergy, no matter the material. At the moment, Eric Parsons is my zenmaster and is solving my luggage needs, including waterproofing and unusual volumetric needs.
Eric Parsons at Revelate Designs was responsible for a large chunk of my storage needs including Tangle frame bag, gas tank, feedbags and front harness with large pocket so I certainly am not going to argue with your zenmaster assessment. 🙂
I haven’t completely given up the old ways, however, and marry the svelte bikepacking gear with mini-panniers (Arkel Dry-Lites) and an Arkel Tailrider on a Tubus Logo rear rack somewhat like Russ has shown at The Path Less Pedaled: http://pathlesspedaled.com/2015/07/review-small-pannier-shootout-ortlieb-salsa-and-arkel/ . Hybrid set ups work for some of us!
It looks like Scott at Porcelain Rocket is also now churning out mini-panniers (with separate waterproof liners for them as well): http://www.porcelainrocket.com/introducing-micro-panniers/ (see comments section for reasons for using) + http://www.porcelainrocket.com/product/micro-panniers/ + http://www.porcelainrocket.com/product/micro-pannier-waterproof-liner-set/ . The best part about the new PR micro/mini-panniers? There isn’t the usual 12 week wait for them (at least at the time of writing)!
Great post! thanks for listing Alpine Luddites. one correction, we are in Ouray Colorado, not Gunnison.
