Ultimate Direction Running Mountain Hydration Vest 6 UD Blue, S

A rocky, steep descent with the poles stowed leaves no hand free for fussing with gear, and the Running Mountain Hydration Vest 6 is a trail running hydration vest with 13 liters of carrying space. A weather-resistant main pocket opens clamshell-style on the back, and a rear compartment takes a 2-liter reservoir if one is preferred. What Our Gearhead(R) Experts Are Saying:"On a hot day of steady climbing with full bottles up front, this vest never bounced or shifted, because it wraps around my ribs like a second layer instead of hanging off my shoulders. I snugged the sternum strap once at the bottom of the hill and never touched it again."
