UltraFit nylon straps (20 mm) are lightweight, flexible and comfortable. They are made from a double-layer, antimicrobial nylon stretch fabric that allows moisture to escape. The strap wraps around the pins and is secured by two sets of Velcro straps at each end of the strap, allowing easier adjustment and a secure fit for a variety of wrist sizes. UltraFit nylon straps offer reliable performance, superior comfort and durability.
