The UltrAspire Stealth Race Vest is a minimalist, lightweight performance race vest designed to thrive in fast-paced race environments. The Stealth features 7 pockets strategically placed to allow access and gear prioritization. The pack’s MaxO2 Form adjustable closure system secures and adapts to the pack’s load. This innovative system can conform the pack to the body using a single pull. Similar to the MaxO2 Sternum, this system allows the pack to remain secured without impeding natural breathing. The side pockets feature magnetic closures to keep contents secured, and the front harness is equipped with an additional open mesh pocket and a zippered pocket. Included with this vest are 2 300 mL Softflasks that fit perfectly into the main harness pockets while keeping the footprint as minimal as possible. Available in 3 sizes to ensure a perfect fit.
