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.

I bought this replace the strap on an old polar pacer. This is supposed to be the proper replacement, but the plastic ends are smaller than the originals and the fitment is sloppy. I simply replaced the new ends with the old ones by sewing them on and it works well now.

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

It said medium but had to be a child's medium - had to reorder and finally got the " medium"

Exactly what I needed to replace my old strap that had lost all it's elasticity. But the coolest thing is that I ordered it from my phone while on the elliptical machine (I kept forgetting when I was home), it was only four bucks, free shipping, and it arrived in only 4 days.

Replacement straps elsewhere are over priced. This was the right product at the right price point. It would be nice if I didn't have to replace it at all.
