With a Polar Loop strap, you can give your Polar Loop a different look. These straps are specially made for the Polar Loop. You can choose from various colors: black, beige, green, orange, blue, and brown. The strap is made from nylon. This way, it's comfortable and dries quickly if the strap got wet. With the velcro closure, you can firmly close the strap around your wrist. You get 2 sizes by default: S/M and M/L. That way, you're sure the strap fits around your wrist.
