Alpha 3.0 Pitch Black [Size: Large]

The Alpha 3.0 hydration pack is a minimalist, form fitting race vest that is comfortable for trail races up to 100 miles or for long training runs. Finally, a vest where you can comfortably reach into the back pocket, with either hand. The Alpha 3.0 comes standard with two UltrAflask 550 Hybrid Bottles included and has the capacity to hold a 2L reservoir if you wish. Now with a large zippered back elastic mesh compartment at the rear for more capacity and security, the Alpha 3.0 has all the features of the original award-winning Alpha and more.
