The GTD Belt V2 is a progressive running belt from Korea's CAYL. Utilising a unique double-pouch design, there's space for hydration bottles, gels, snacks, phones, trekking poles and whatever else you need with you on your trail runs or hikes. That easy-adjust bungee cord system keeps the weight down while those breathable mesh back-panels aid breathability on hot days. If you're after a hands-free haulage solution for high-speed trail action, then this left-field design might just be the one.
