+10 bar none! We have had snow the past two years up their at that time a little more east of their. Something rated even colder maybe -10 might even be wise! That or get one of those polar fleece inserts. Its better to have and not need then to not have and need dearly! Espically in a harsh environment like the slope!

It can be very nice or spitting snow both within a day!

I prefer fleece and use my rain gear as a wind break when not moving. when moving it helps keep me ventalated, warm, and when wet drys fast. I prefer poly pro long undys as they are warm as heck. One catch is they hold scent bad! you can stink up pretty quick in them.

I also have some wooln' s I really like. Usually keep them for the october hunting though.

If you dont mind me asking what outfit are you going out with?
