Is your ass cold? Seriously, if the chairlift seat is cold (covered with ice? lifties not sweeping the seats?) you can lose a lot of heat thataway. When I put on my impact shorts and my spine protector I feel WAY warmer on the chair simply because I'm more insulated from the seat.
Off topic, but do those impact shorts really help much on falls? I've been thinking about ordering some. I have not really injured myself on falls but I'm kinda pushing it more in the park this year. I've thought about getting some.
OP - If I was wearing that much I'd be sweating like crazy! You might have to just cry like mixie suggested!
