The UltraFit 20mm nylon strap is light, soft and comfortable to wear. It is made of a flexible two-layer antimicrobial nylon fabric that allows moisture to evaporate. The strap wraps around the pegs and is attached at both ends with two velcro straps, making it easy to adjust and improve the fit on wrists of many sizes. The UltraFit nylon belt is very reliable and durable.
