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

The garment can be worn on its own on milder days or as an effective insulating layer beneath a shell jacket when the temperature drops. The front zip makes it easy to regulate temperature, and the combination of materials makes the garment both lightweight, technical and comfortable next to the skin.

Additional sections of pure merino wool in parts of the construction provide greater warmth and increased comfort without compromising breathability.
