Fuel Belts are a huge breakthrough in performance hydration!  Fuel Belt went full tilt with the highest quality materials and added some unique features to further enhance what was already a solid product. Take a closer look and you'll notice the highest quality reflective material for low light conditions. The bottle cord locks to secure the bottles in place and the spacious rear pocket holds small items. More runners are using Fuel Belts than all other bottle carriers combined. (To ensure you order the right size, we strongly encourage you to measure your waist or hips, depending on how you prefer to wear your belt).
