Icebreaker Merino 300 Realfleece™ Descender LS Zip is a warming and versatile mid-layer developed for high-intensity use in cold weather. The soft blend of merino wool and TENCEL™ provides natural breathability, effective moisture transport, and an insulating feel that keeps you comfortable during running, hiking, and other demanding activities.

The garment can be worn alone on milder days or as an effective insulating layer beneath a shell jacket when temperatures drop. The front zip makes it easy to regulate temperature, and the combination of materials makes the garment lightweight, technical, and pleasantly close to the skin. Additional panels of pure merino wool in parts of the construction provide greater warmth and increased comfort without compromising breathability.

Material: 60% TENCEL™ Lyocell, 40% merino wool.
