Description Our 100% Merino wool Inversion Bottoms are long johns made for layering in the coldest conditions. They fit great, wick sweat, breathe well and resist odor, so you'll be comfortable and fresh all day long. We made these for winter sports like skiing and snowboarding, but they work great for any outdoor activity or under everyday pants in cold weather. We're not the only ones who love these long underwear — Men's Journal and Backpacker Magazine have praised them too.
