Body Conforming Fit for Baselayer Flat Seam Construction for Seam Strength and to Eliminate Abrasion Multi needle Covered Elastic Waistband in Bottoms Men39s and Women39s Sizes Available Men39s and Women39s Sizes Available Hot Chillys Micro Elite Chamois Long Underwear is a body fit and has a warmth factor of 8. Micro Elite Chamois is very versatile. A technical blend of 44% micro and 44% macro polyester and 12% Lycra yarns combined with a patented knitting process makes this product the perfect layering piece for cold weather days. It is extremely warm for its weight 8 and can be layered for winter sports use, as well as everyday dressing. The fiber combination expedites the movement of moisture away from your skin for rapid evaporation. A soft chamois finish on the back adds softness to the feel of the garment. This product is very similar to the original Hot Chillys in a can, except that it does not have the stirrups for the feet which most skiers and boarders do not want.
