I know I'm going to sweat underneath the RIBZ if I wear them. Do the items in the RIBZ get all sweat soaked?
If you sweat like me, your RIBZ is going to get drenched and will be musty like my athletic jock rather quickly. I'm glad you brought this up. Come to think about, I would only want to use a RIBZ in the snow or other cold environment. Unfortunately, I already established I would not want to snowboard with it. That leaves snow hiking, snowmobiling or other. I can certainly see a use there.
I've heard that 1 in 4 people sweat profusely. I'm one of these people. People who don't sweat much don't understand it. They say ignorant things like "you need to get in better shape" or "you drink too much water". It doesn't matter what kind of conditioning I have or how much water I do/don't drink. When I start to sweat, it's coming out at least 10 times faster than a person who doesn't sweat much.
