One of our most popular running vests just got an upgrade. The new version of the Circuit is 30% lighter and includes a 1.5-liter Crux reservoir that delivers 20% more water per sip.
And of course, it still offers all of the features that make it a favorite for bonk-free races and long runs: front storage pockets for gels and fuel, a secure zippered pocket that fits most phones, and reflectivity to keep you visible when you’re on the move. The two fully adjustable sternum straps guarantee a snug, bounce-free fit that won’t constrict your breathing when you’re panting through a hilly workout.
The brand new Crux delivers 20% more water per sip, with an ergonomic handle for easier refilling, and an on/off lever that makes it easy to prevent leaks
Front pockets are compatible with our new Quick Stow flasks that are lightweight, collapsible and feature our classic one-piece silicone bite valve for rapid hydration on race day.
3D Ventilated mesh offers multi-directional air flow and cushioning to maximize comfort and breathability
Secure phone pocket conveniently located for quick access and includes a zipper closure for added security

When all you want is water, this minimalist bike pack has you covered—enough water for a 2-hour ride, and a safe zip pocket for keys and essentials. The new Crux™ reservoir also offers 20% more water per sip for faster hydration in the saddle.
For hands-free hydration, our lightest hydration belt stores a 17-oz Quick Stow flask with soft walls that mold to the shape of your body. The 3D mesh material stays light and breathable on even the hottest runs, and the extra stretch pocket keeps gels, keys and cards safely tucked away. Plus, you won’t be stuck carrying a big empty bottle at the end of your run—once the flask is empty, just fold it up and tuck it away.
