On the days when the heat and humidity are practically unbearable, the Women's Spark Tank is your most comfortable running companion. This minimal tank is built from Cool-Lite™, Icebreaker's exclusive blend of merino and TENCEL®. Cool-Lite™ keeps you cooler and wicks away sweat better than cotton, wool, or even Polyester. Compliment this fabric with super lightweight eyelet mesh on the back, and bonded seams, and no matter how hot and muggy it is, you'll be, well, a lot more comfortable than your other running companions.
