Being too warm is actually a significant drawback to those. Since I think the o.p. skis alpine, not tele, and doesn't ride, and is talking off-piste, not doing rails, Crash Padz don't make much sense in terms of likely impacts either. My recommended list of safety gear for someone with that itineray would be (fullface) helmet so that you can feel comfortable skiing faster than you other wise would through tight EC trees and maybe hook the fullface; spine protector so that you can suffer heat exhaustion and also feel good going faster than you otherwise would through EC trees and, as a bonus, feel good about a bony chute out West you normally wouldn't consider; wristguards so you can feel comfortable trying to stop yourself in those trees with stiff outstretched arms; kidney and rib protection as part of the spine protector to make heat exhaustion arrive more quickly; and by the end of the season fungicide to help deal with the side-effects of those funky, moist and sweaty pads. Then a kneebrace for both knees because, while the consensus of leading sports docs is they don't help protect non-injured knees, they are a way of signifying radness and are endorsed by some well-known athletes who get paid to wear them. Then and only then, maybe, impact shorts to complete the package.
