I have a 661 Pressure Suit, but it's uncomfortable, very hot, and doesn't fit that well, and I don't have enough money to replace it with something else. Fortunately, I have a pretty-new Thor motocross chest protector laying around my house. Do any of you ride DH with moto armor? If so, how well does it work? Has it been enough protection in your crashes? My main concern is that there is no foam covering your spine (only plastic), so it doesn't seem like it would work that well if you fell hard on your back, especially on something fairly pointy.
