Minimalistic! The lightest and most minimalist hydration belt accommodates a 0.5L Quick Stow bottle that conforms to the shape of your body. The 3D mesh material remains lightweight and breathable even during the hottest runs, and the additional stretch pocket securely holds gels, keys, and cards. Plus, you won't have to carry a large, empty bottle at the end of your run - simply fold the bottle up and stow it away when it's empty. For more technically demanding runs, there’s even an integrated trekking pole holder.
