Strap tension is fully adjustable, allowing you to tighten or loosen for a custom fit. The cuffs are padded for comfort during wear and removable for flexible configuration options. Quick-release velcro fastening enables easy on-and-off operation. A central carabiner design with removable straps supports multiple positioning options. Material: Nylon. Color: Black.
