I am going snowmobiling up in the Truckee area of Tahoe this weekend & was wondering how my BMW system 2 suit would work for sledding. It is either this or traditional ski bibs, ski jacket & sweater... This is kind of new for me, so I'm not sure if the gear would work fine, I mean, it is fairly waterproof, isn't it? I do have proper boots at least already. I envision temps ranging from the 20's to 40's in the sun. It shouldn't be a wet day.
