Everything you need for short bursts in the high country. 5 liter capacity means an even smaller load and even less load shifting. This is optimized with the stretch panels that help keep the main compartment compressed and the bungee strap across the chest that keeps the shoulder straps firmly in place. The Trail Vest 5 is equipped with a water bottle holder on the left shoulder strap, elastic pockets for gels and accessories on the right shoulder strap and external loops to attach extra bungee cords to carry extra gear. Breathable mesh on the back and shoulder straps is optimized to deliver superior comfort even on the hottest days.
