USWE Vertical Hydration Pack 4L




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's different about this pack?

The Vertical 4L is a comfortable but capable multi-sport hydration pack specifically developed for any adventure. It's one of the best fitting packs they offer and comes in the sweet spot of 4L of total storage, including a 2.0L hydration bladder. That means you can carry spare gear, snacks, and any essentials without stuffing pockets or being weighed down.

If you're unsure where to start, this pack may be the answer. This one is simple and effective.

  • 4L total storage
  • Weight: 300g (*excluding bladder)

What’re my options?

How do I use it?
