While built as the perfect running pack, the Zygos is suitable for all occasions—from extreme mountain ultra scenarios to biking, skiing, and even, motorcycling.

This new design for late 2015 includes the new soft touch binding, large capacity quick stash pocket without added weight or bulk, quick attach bladder holder, new elastic mesh on quick stash pockets featuring more stretch, added
capacity, less bulk and weight.

Soft, large holed, micro-fiber fabric enables excellent circulation, cooling and breathability throughout the vest; and, the amazing trademarked and patent pending Max O2 Sternum™ system is super easy to get in and out of, with or without gloves, even with tired or fatigued fingers. Once adjusted for proper fit, there is no slippage or change in tension. It’s the only system out there that allows for full movement through the chest and unrestricted deep breathing without any loss of stability, you know when your working hard running up a mountain trail.

Have a breezy, easy feeling in the most human compatible vest system ever built.
