The FlipBelt Classic Carbon is designed to hold your items securely and comfortably while you train. Its tubular design sits flat on your hips without bouncing or riding up, eliminating the need for buckles that can cause chafing. Simply pull it on like a pair of pants, over or under clothing, and slide your belongings through the multiple openings. It can comfortably hold a phone. Turning the belt over secures your items. It is recommended to measure your hip and waist circumference where you plan to wear the belt, as measurements may differ. Available in various sizes: S (26-29" / 66-73cm), M (29-32" / 73-81cm), L (32-35" / 81-89cm), XL (35-38" / 89-96cm). Features include moisture-wicking, quick-drying fabric with extra softness, an internal key hook for security, multiple pocket openings, and a 3M Quality reflective logo. Care instructions: Machine wash and dry, or hang dry. Material composition: 92% Micropoly, 8% Lycra. This belt is a comfortable alternative to armbands that cannot hold all your gear and bulky running pouches that bounce. It is made from moisture-wicking fabric that stretches to fit large phones. The FlipBelt is ideal for running, hiking, biking, gym workouts, travel, and more.
