Go minimalist on your trail run without skipping on hydration with the CamelBak Nano 3L Vest. This lightweight vest has you covered when you start to feel parched, with two Quick Stow Flasks that equip you with thirst quenching goodness when you need it most, and ultra-breathable construction that keeps you cool when your feet are pounding the dirt. Instead of hosting a bulky back reservoir like many hydration vests, the Nano 3L skips over big pockets and bladders for a mesh back that breathes with ease, and features slotted storage for packing your trekking poles out of the way, but easy enough to access with one hand while running, in case the trail ahead sends you up a spontaneous rock face. Two straps secure the vest in place in front with adjustable clasps that fit a huge range of sizes, enabling any runner to dial in a comfortable fit.
