Anyone got one of these?

Looking for some lighter weight armour for summer in the alps, liking the look of these, maybe combined with some 661 evo knee and elbow pads.

The description doesn’t say what the padding is made of, I am kind of assuming that it is some sort of d30 type material. Does anyone know for sure? And does anyone have one and would like to review it?
