Look more comfortable than are in reality to wear. Only the shorter section of the straps that go to the back section of your pant  are elastic. The longer section of strap is made of a cheapish non elastic plastic. I found the plastic straps to be a bit too slippery for my shoulders and needed to adjust the suspenders often because of slippage. Also after only wearing a few times I found that the plastic strap was piling in a one spot.

On the positive side these braces have very strong buckle grips (or whatever you call them). The straps appear to be very strong as well.

Good work suspenders but not so good general wearing suspenders.
