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.

Our most technical running pack, the Ultra™ 10 was designed to endure one of the toughest trail races on earth: the Ultra Trail du Mont Blanc. We engineered this pack to carry every item on the UTMB gear list: a 2 liter reservoir, room for food and extra layers, a sweat-proof pocket for your smartphone and two chest pockets for additional water bottles. If it works on Mont Blanc, it can handle just about anything. Refilling on the run? We’ve added color-coded straps so you’ll instantly know how to access your water supply, and an external-fill design that lets you refill without unpacking the bag. On hot days, fill the reservoir with ice water—the mesh back panel lets it sit against your back to cool your core.
We’ve also included overflow storage, trekking pole attachments and plenty of lash points, just in case you want to bring something we didn’t think of. The custom-fit harness and dual sternum straps adjust for a close, comfortable fit, and the cargo compression lets you cinch everything down to minimize bulk.
The Lobo is ideal for days when the weather is clear and the trail is calling—days when you want to ditch most of your gear to travel fast and light.
With 3 liters of hydration capacity, it carries enough water for a substantial 3+ hour ride, and the external fill means you can top off the reservoir without unpacking anything.
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.
