Spry 5.0 Running Vest Blue

The Ultraspire Spry 5.0 is the gold standard for minimalist race vests, refined for even better comfort and durability. This award-winning pack is designed for runners who need to carry the essentials without feeling weighed down. Featuring a 3.5L capacity and a smart 4-way stretch mesh main compartment, it expands when you need to stash a layer and compresses when you’re flying light. With the inclusion of a 1L reservoir and a sweat-proof liner to keep your gear dry, the Spry 5.0 is the ultimate "grab-and-go" rig for everything from local trail loops to competitive ultra-marathons.

• Sweat-Proof Back Panel: Features a specialized liner under polyester mesh that keeps the contents of your pack dry while remaining breathable against your back.
