I wanted to replace my Domyos protective shell that I used last year for the practice of Krav Maga. I turned to this one after reading the comments and advice of my teacher and I'm not disappointed at all. Perfect adaptation to the morphology, I hardly feel the even running. At impact it's happiness, while my Domyos caused me a rebound because not enough down in the groin, this protective shell fits perfectly and the absorption of the impact is all the better. Possible to use it without slip directly between the skin and underwear without worry.
