📐 ✂️ - Thoughtfully designed & built to last We are inspired by cycling and make bags for traveling.

Whether it’s for one hour or one year, the spontaneity of a plan can be necessary and/or rewarding. That's why most of the bags can expand to higher volumes and adapt to different situations. Founded in 2015, Outer Shell focuses on the highest quality gear with function forward design, backcountry security and minimalist style. We design for versatility, durability and repairability, using fewer s

The Koozie origin lore ✨

Over the last 5 years or so, a growing pile of scraps was slowly taking over our studio, ~100 yards of random bits of fabric 😳

These were smaller remnants and the ends of large rolls, that were too small to use in our normal production cutting process.

It would have been a huge waste to throw it all out, so we got to puzzling designs onto the off-cuts and turned all that fabric into something cute, useful, and fun!

True to OS principles, we couldn’t just make a normal one. Ours folds flat cleanly, features a hand-hugging webbing handle, and has handy attachment points for a carabiner or Nano Voilé strap.

Fabric’s on us for these — you’re just covering parts and labor. Thanks for helping us clean up the mess!

Seems like Manuel Barra rides to LA every other week now 😵‍💫

Doing it a little different this time tho. Going fast and light with our Half Framebag and Rolltop Saddlebag packed with fuel and tubes on a Quick Pro US Zeit from Lux Bicycle Shop🇲🇺. Let’s see if he can do it in one shot!

He’s also raising some funds for men’s mental health so give him a follow for more info.

If you’re looking for something that transitions seamlessly from on-bike to off, it’s tough to beat our Magic Tote and Magic Musette 🪄

Both are made with incredibly lightweight and super strong recycled Ultragrid fabric from Challenge Sailcloth, have adjustable stabilizer straps, and pack down into their interior pockets when not in use.

The Magic Tote ups the capacity to 10.4L, adds huge external pockets, a stylish climbing rope main strap, and a sweet little stretch pocket for the stabilizer strap so it’s not dangling when you’re on foot.

Thanks to Dismount Bike Shop for these photos. Give them a visit next time you’re in Toronto!

Tomorrow! We are opening our doors to the public to share this little stronghold of San Francisco known as The Farm. If you didn’t know, we work in a space that’s had half a century of creative community. Our current unit was once Subterranean Records, an independent label that released bands like the Dead Kennedys and Flipper. MDC, Black Flag, the Descendents, Discharge, and Bad Brains have played here, to name a few. Sadly, Steve of Subterranean was forced to retire, but we hope to continue the legacy of DIY ethic and we thank all the artists that have paved the way for this space to exist.

Currently, the Farm houses .scorps .creative and many other artists. Come see our space and be a part of it. I hooked up some speakers and a tape deck recently. If you have cassette tapes, it would be fun to bring them.

We’re also having a sale online and in person so you can come shop as well.

Is it so bad to be vain? We hope everyone got to ride their bike today and feel good about themselves. Sometimes you gotta look good on the outside to help your insides be good too. Bikes are cool and so are you for riding them. 😎

Our friend Lauren just got this super stylin’ AND practical Serotta built up. Fully accessorized, serving up all the vibes.
