In 1985, Hot Chillys introduced the very first body fit thermal base layer. Their mission? To keep you so comfortable you forget your base layers are even there. Hot Chillys' garments are designed for the best possible fit and to choose fabrics that pass rigorous performance testing for quality and wearability, whether you are on the slopes, in the field, and everywhere in between. They're the first to sell out at Bob's when winter comes, so get them while they last!
