The Ultimate II Running Belt is the first belt of its kind to incorporate a pouch, gel loops, and bib toggles in one refueling belt. The patented design allows you to carry enough fuel to go the distance without compromising on performance. Great for all endurance sports like marathons, triathlons, hiking, and more. Like all our running and fitness belts, the Ultimate II is meant to be worn on the widest part of your hips so that it does not bounce, chafe, or ride up.
