## Description

Polar soft strap the Polar soft strap is the most comfortable chest strap for measuring your heart rate. Comprised of soft fabrics covering the adaptive sensor, the strap is extremely sensitive to your heart's signals, meaning that readings are quick and accurate. Compatible with all Polar heart rate sensors that use the snap attachment method. Size M-XXL fits a 26-36 inch chest.

Review: Worked as expected. Brought my heart rate monitor back to life. - Started getting erratic and no readings from my heart rate monitor and battery replacement was not helping. The only thing I had not done up to that point to try and get it to work was replaced the strap. Polar products are awesome however they don’t last forever. The strap is probably going to be replaced before anything else. After replacing the strap, my H 10 heart rate monitor worked as expected. These are pricey, however, they are absolutely essential in the correct operation of your monitor. Most likely the thing that led to the downfall of my original strap was it was accidentally run through the clothes wash. Never do that.
Review: Excellent quality, quick-release clip - I'm a big guy and I needed an XL strap for my Polar H10. This was the best option, and it fits with room to spare. After sizing to Polar recommendations (6" gap when loosely wrapped around the chest), and clicking it shut, it practically disappears. In fact, after a workout I find myself checking to see if I have removed the strap or not! Very comfy, very well made, with "grippy strips" on the inside to improve fit. You won't be disappointed.
