Hot Chillys combined pure Merino wool with mtf fibers and added spandex to create a baselayer hybrid that is warm, comfortable, and easy to move in. The natural Merino wool yarn is inherently thermal retentive. It traps air in its fibers, keeping insulating warm air close to your body. The natural wicking properties of wool are enhanced with our mtf fibers so moisture is rapidly transported. We designed this collection for a "next to skin" fit, eliminating any excess fabric to enhance performance.

Mtf (moisture transfer fiber) wicks energy-sapping perspiration
