The Old School Carry-All (OSCA) is reissue of a TOM BIHN duffel design of the 1990's with a few important design updates.
Back in the 90's, Tom designed The Classic Sport Bag in answer to customers' requests for a bag to take to the gym.Though it was well-loved by many customers, there was some legitimate feedback about the Sport Bag that Tom has taken to heart: specifically, folks wanted separate and substantial compartments to segregate and/or organize their stuff.
So, Tom turned the simple flat pockets on the sides of the Sport Bag into the generous 3D side pockets of the OSCA; this also allowed us to make the padded handles on the top of the bag lean in towards one another (“kiss” as Tom says), making them easier to grab. We updated it with lots of O-rings to tether pouches, keys, etc, and added webbing grab loops and two places on the exterior to latch a carabiner as well. You can read more about the design and manufacturing of the OSCA in this blog post:
Today, we're calling it the Old School Carry-All because we've found it to be useful for so much more: carry-on travel bag, road trip duffel, overnight bag, back-of-the-car organizer and yes, even as a bag to take to the yoga studio or gym.
