USWE Flow MTB Protector Pack




What we think

USWE (pronounced - YOU-SWEEE) makes one thing: phenomenal product. 

Lately, if you've been paying attention to some of the racing scene, you've seen these on some world-class athletes crushing events like Leadville 100, UNBND Gravel, or SBT GRVL.

USWE makes bounce-free action packs that provide the perfect fit on an individual level – developed and tested together with top athletes, pro mountain bikers, and core weekend warriors since 2007. Their mission from day one is to design packs that you can wear in action with a super-snug race fit.

What makes this pack different?

Tailored for the aggressive adventurist, the Flow 16 and 25 are your dependable companions for protecting your back and gear on MTB adventures in rugged terrain.

As part of the Protector Pack series, this is a practical MTB backpack that instills confidence and safety through the removable multi-compliant CE-certified SAS-TEC central back protector (SC-1/CB52). Crafted from flexible viscoelastic foam with a "memory" effect, it quickly regains its shape after absorbing impacts or deformation, ensuring your safety during unexpected challenges or falls.

This pack was designed to make your big mountain bike days easier, too. You can take a break or use transit and attach your helmet to the back of the backpack. It also incorporates many features of the Shred pack, including rain fly and armor attachment points. They've thought of it all with this one.
