Use the FlipBelt Classic Carbon to hold items securely when training. The FlipBelt is designed to easily, comfortably and securely carry everything you need while you train. The tubular design is made to sit flat and securely on your hips without bouncing or riding up. With no buckles to pinch or cause uncomfortable chafing, just pull FlipBelt Classic on like a pair of pants, either place it over or under your clothes, then easily slide in your stuff through the multiple openings around the belt; it can hold a phone comfortably. Turning the belt over closes all openings and further secures your items in place. Make sure to measure your circumference where you plan to wear your FlipBelt. Your hips and waist may have different measurements. Size Guide S 26-29 67-73cm M 29-32 73-81cm L 32-35 81-89cm XL 35-38 89-96cm. Moisture wicking, quick drying and extra softness against your skin.
