The Strive Fly Trail Running Backpack is Silva's sleek and super lightweight running marvel! The sporty and functional running vest is made from breathable and lightweight ripstop material, ensuring optimal mobility and ventilation. The Strive Fly Vest is barely noticeable while running, thanks to its two adjustable chest straps and thoughtfully placed pockets, compartments, and straps. It features four front pockets, a spacious and easily accessible mesh pocket on the back, and two side pockets for additional small items like gloves. Additionally, there are two movable and adjustable straps for water bottles and straws, as well as four more movable and adjustable straps for securing trekking poles or other items. Clearly, with the Strive Fly Vest, all focus is solely on the run!.
