The Speed Belt 4 is the ultimate mobile aid station, which comes with four 10 oz. nutrition flasks that fit perfectly into the moulded holsters, allowing quick flask access. This speed belt also has front and rear stash pockets for small essentials. The airmesh moisture wicking lumbar backing material is used which pulls moisture away from your body, increasing comfort and reducing potential chafing. The limited stretch elasticized waist belt with a soft perimeter binding helps to access the bottle, as well as to aid in better belt placement and unrestricted movement. The weight of this speed belt is distributed evenly around the belt.Available in three sizes: - SM 26-32, MED 32-36 & LG 36-42.
