Heart Rate Monitor Replacement Chest Strap Compatible with Myzone MZ-Switch Chest Blet ​Multi-Packs

these are very comfortable and just the right amount of stretchiness

Great construction! Holding up significantly better than the strap provided with the MYZone heart rate monitor. Elastic is a little thinner however, does not present an issue. Appreciate the 2 pack... allows switching every other day for drying purposes.

They don’t fit the MyZone device. The holes are too close together. Wasted money

I am rough on my MZ straps. I can't stand the smell when they are sweaty so I am always washing them which causes them to breakdown easily so I am often in need of replacements. That can get expensive. I love these replacement bands and I love that there is both a red and a black. This keeps mine and my husband's separated. It works for the MZ switch, but not the old style.

These Rich Green Valley replacement heart monitor chest straps for the Myzone MZ-Switch are of good quality. They come two to a pack - one red and one black.I ordered the size medium. I measure 37inches around the chest - as measured under the pectoral muscles. (Refer to the listing photos for exactly how to measure the circumference of your chest.) The medium size fit perfectly with plenty of extra strap left over for if i were several inches larger.With exercise sweat being a thing, it is a good thing to have extras of these on hand

I thought this said it did fit the MZ-1 and 3 myzone devices but I must’ve misread. These do seem very high quality though so I’ll still give them a good rating off of that, and I was very excited to get a black band over the red my myzone device came with.
