This tack is very comfortable to wear, the belt does not slip down while running. The compression effect is great, I wonder if I can put shorts when the weather is hot, compression will miss it ... We must obviously choose between morphology "A" or "H". Temperature control is perfect, although I have not tried by -to 3 ° C (I do not run when it freezes, and he has almost never frozen this winter ...!). Held at impeccable washing. In short, that happiness !!!
