The ZoneKnit Short Sleeve Tee is icebreaker's most breathable and lightweight active tee designed for running, biking and other high-exertion activities. This lightweight tee features ZoneKnit engineered body mapping, combining Cool-Lite jersey fabric with strategic panels of Cool-Lite eyelet mesh on the back and sleeves for enhanced breathability and temperature regulation when you're on the move. Offset shoulder seams reduce friction when wearing a pack.

Silky-soft merino and TENCEL sourced from sustainable eucalyptus plantations, combine to create icebreaker Cool-Lite, a luxurious fabric that naturally regulates your body's microclimate. Inspired by nature, icebreaker harnesses the performance qualities of natural fibers to offer an alternative to clothing based on petrochemical synthetics.
