I guess the acid test with this stuff is when you go down the road on your arse in it. However, I’ve replaced the standard D3o level 1 stuff in my Baja S4 jacket and troos hips with it. You get level 2 protection in a more flexible, no thicker and well-fitting package so what’s not to like?
also replaced the bulky and not very breathable Knox level 2 in my Pro Tube knee protectors with another set of Diablo. Same protection, much less bulk.
If it works, it’s a total winner IMHO.
