Replacement wristband Polar nylon with Velcro fastening 20 mm black M/L

Replacement wristband Polar nylon with Velcro fastening 20 mm black M/L is a compatible accessory designed for daily wear and sports use. The strap is made from durable woven nylon and uses a hook-and-loop (Velcro) closure system to provide an adjustable fit. With a 20 mm lug width and a medium/large length, the band offers quick attachment and removal and is intended as an alternative to worn or damaged original straps or as a style change for compatible Polar devices.

Advantages

The nylon construction combines strength and flexibility for regular use, while open weave and breathable fibers help reduce perspiration build-up during exercise. The Velcro fastening enables micro-adjustments for a secure fit and fast on/off, and the 20 mm width matches common lug sizes for straightforward replacement. The black colour gives a neutral, unobtrusive look suitable for everyday or athletic settings.

• Replacing a worn or damaged wristband on compatible Polar watches and trackers

• Sports and training sessions requiring a breathable, secure band
• Users who prefer an easy-to-adjust hook-and-loop closure

How to use

Remove the existing band from your device according to the manufacturer's instructions and attach the replacement nylon strap by aligning the 20 mm ends with the watch lug connectors. Secure the strap around the wrist by pulling the free end through the loop and fastening the Velcro surface to achieve the desired tightness. To remove, peel the Velcro apart and detach the strap from the device connectors. Clean the strap with mild soap and water when necessary and allow it to air dry before reattaching.

Usage recommendations

For best performance, ensure the attachment points are compatible with a 20 mm strap and regularly inspect the Velcro surface for lint or wear; keep the hook side free of debris to maintain secure fastening. Avoid prolonged immersion in water with repeated exposure to chlorine or salt without rinsing and drying afterward to preserve the nylon fibres and fastening function.
