On entire buttocks no trace of protector, the coccyx of use has only half the strength and is perforated, in my opinion, no real protection against tailbone bruises. And a substantial portion of the femoral neck is completely unprotected. The thigh sides are very well protected, but that there is always so much muscle that I could do without protection there even.
So for people who always fall just to the side to use the part certainly, but for snowboarders as I rather fall on the butt, no suitable protection. I then also returned the shorts.
