ACTIVE FIT - Designed to follow the lines of the body, usually with some amount of stretch fabric. These garments have a lighter feeling fit, with less bulk than a relaxed fit thermal base layer. They are especially perfect for year round, multipurpose use under layers.
UPF 40+ - Ultraviolet Protection Factor. Sunlight includes rays of ultraviolet (UV) radiation, and Hot Chillys products are designed to help protect you!
WARMTH FACTOR 10/10 - Ranked from Mild to Hot, the Warmth Factor Thermometer tells you how warm each of our products is. Warmth Factors 6, 7, and 8 are considered Midweight and are very popular for most cold-weather activities.
4-WAY STRETCH - Fabrics with this elastic feature will hug your body and move with you, eliminating extra bulk, providing a full range of motion, and improving performance. Nearly all our body-fit products include a 4-way stretch. Some of our relaxed fit products include a 4-way stretch as well.
MOISTURE TRANSFER FIBERS - An essential feature in all our products, Hot Chillys exclusive moisture transfer fibers (MTF) move moisture away from your body by employing hydrophobic yarns to wick away perspiration, thereby keeping you dry and comfortable.
