The Hot Chillys La Montana Men's Zip Long-underwear top is extra warm, body-fit long-underwear with a warmth factor of 10 out of 10 on Hot Chillys' warmth chart. La Montana is Hot Chillys' warmest offering. The micro denier fabric provides added wind and water resistance while trapping less air than bulkier products. It breathes easy, is exceptional at wicking away moisture and may be thrown in the washer and dryer repeatedly.
La Montana feels and looks like fleece, but it features a more technical construction. The fabric is 30% ESP polyester, which creates stretch characteristics, and 70% micro-denier polyester, which moves moisture 40% faster than regular poly. La Montana is virtually windproof. Gussets of a double layer of MTF 3000 AM under the arms help create a great fit.
