A revolution in hydration belts! There has never been one belt with the versatility to carry a lot, a little, or no hydration at all. Great for walkers, trail runners, hikers, and endurance athletes too. The Fitletic Quench Retractable Hydration Belt features exclusive Dura-Comfort Technology and ergonomic design that contours to your body with silicone grippers to eliminate bounce. The water resistant Neoprene pocket holds your phone and essentials (fits most smartphones including the iPhone and Samsung Galaxy). Two patented retractable zippered holsters fit most bottles 12-24 oz (350-700 ml) with pull-tension bottle secure cords and secure tabs for additional bottle stability. This belt has an ultra soft adjustable waist, 2 exterior energy gel loops for on-the-fly access, high visibility reflectors, interior pocket to secure ID/cash, and race bib toggles. Sizes: S/M (24" to 36") or L/XL (29" to 42").
