An incredibly lightweight and breathable tank top for high-exertion days, the ZoneKnit Tank features engineered body-mapping technology to provide optimal ventilation and temperature control. The ZoneKnit features a combination of icebreaker's moisture-wicking jersey Cool-Lite fabric with a panel of Cool-Lite eyelet mesh on the back that helps dispense excess heat. Offset shoulder seams reduce friction when carrying 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.
