IcebreakerHeadwaters Hybrid Merino SS Full Zip - Mens

A technical and insulating mid layer ideal for cool-weather training, the Headwater Hybrid Short Sleeve Full Zip combines a weather-resistant recycled nylon shell with innovative MerinoLoft™ insulation and a soft, moisture-wicking Cool-Lite™ lining. A touch of LYCRA® provides additional stretch, while reflective hits maintain visibility in low-light conditions. Offset shoulder seams and flatlock stitching reduce chafing.

Three layers of comfort in a lightweight layer, icebreaker MerinoLoft™ has a durable, water-repellent shell filled with natural merino-fiber batting, and Cool-Lite™—a luxurious fabric that naturally regulates your body’s microclimate with a combination of silky-soft merino and TENCEL®, sourced from sustainable eucalyptus plantations. Inspired by nature, icebreaker harnesses the performance qualities of natural fibers to offer an alternative to clothing based on petrochemical synthetics.
