I tested several times to be sure of comment that will be: I have not lost a sweat with the belt and even pants. I sweat a lot more without. Being a bit round, my thighs rub a little but with the pants, impossible to go out with, you'd think Robocop, my FISL 5 years made me so no risk thinking that I make with my jogging. As for the smell, even washed 3 times, there is a new smell that does not go. Otherwise it dries quickly after machine (so maybe my sweat was absorbed by the material without my noticing). The size corresponds but matter that falls pants a little, and when I do commes abs exercises or stretches, I'm too compressed, so I can not do them properly.
