Polar Elastic Transmitter Strap Medium (34-55 Inch Chest) for T31 or T61 Transmitter

Wow. I could not believe how much my old strap had stretched and lost it's elasticity (It was at least 12 years old). When this arrived I thought it was the wrong size because it was less than half the length of my old one. But I was wrong. It is exactly the right size and works great and didn't cost much. So I'm still able to use my ancient Polar HR sensor.

I've had my Polar F6 strap for six years.I exercise 4-5 times a week and I still had the original T31 elastic strap.That's how good the strap quality is! It lasted that long!So I finally had to buy a new one as this one was finally stretched and worn out too much.This one seems just as good. Good fit and comfortable.

These straps have a good long life and during non-aquatic workouts they fit easily. However, they will likelyneed tightening for those lap swimmers since when wet they tend to slip during turns. Otherwise they are quite good.

I did select medium as that is what I was replacing, It was definitely tighter than the I am replacing which is to be expected. I maybe could have gone with a large but the medium should stretch out a little bit. I have it adjusted to it longest length. Good product, original polar replacement.

Does not fit Polar Pacer. My Polar watch, which has no other model designations on it, is called the Pacer in the user manual. Polar support told me is that my Pacer has a T31 chest strap so I ordered this. This is skinnier, thinner, and has smaller buttons on the ends. It also has the buckle on the wrong side and the ends are curved.So I ordered some 1" elastic for $3 and I made my own strap.BTW, I got stuck paying the postage to return this. I feel the seller should have made clear that this does NOT fit a Polar Pacer T31 Transmitter

Needed a replacement for my previous one after many many years. Works perfectly. No complaints. All of these straps tend to loosen slightly over time, and you have to tighten, but no biggie.

Did not like to die could not return it cause it's wrong size or exchange it

exactly like the factory strap a at a much lower cost. shipped fast. the band will stretch over time but it came in snug and comfortable

Worked well for my purpose. The last strap lost its elasticity. This makes the heart rate monitor work well again.
