From mile one all the way to mile thirteen, the CAMP USA Trail Vest offers on-the-go hydration and storage for all of your trail running necessities. The Trail Vest is fashioned with hardy, nylon ripstop and mesh for long-lasting breathability. In addition to its generous, hydration-compatible main compartment, this vest boast a myriad of elastic pockets that accommodate gels, snacks, and a water bottle. The bungee strap across the chest keeps the vest secure and deters any movement or potential for hot spots--which is awfully convenient when you're running down the trail like a bat-out-of-you-know-where.
