Have you really ever been on the mountain?! Sweat pants? Cotton?
Do yourself a favor - Under Armour Cold Gear - the $100 for top & bottom is well worth the
investment. Buy SHELLS only - pants & jackets. If you just so happen to be heliskiing somewhere
where it is -20 degrees, throw a layer of polypro fleece on.
Very simple. LEAVE THE COTTON AT HOME!!
... sweatpants... really?
