Our focus should be on the trail and not on the bag that keeps bouncing around on our backs. Luckily we found the Epic 3 Hydration Backpack. USWE's unique No Dancing Monkey support latches to us like an orangutan to a branch, meaning no bouncing and a tight grip. The coupling system stays close and at-the-ready so we can get water at a moment's notice, ensuring we spend less time out of focus.
