Columbia

Zero Rules Cami - Women's

As a general rule, running makes you hot and uncomfortable, which is why Columbia made the Zero Rules Cami. The Omni-Freeze ZERO technology reacts when you sweat, lowering the temperature of the fabric and keeping you cooler longer. The Omni-Wick treatment pulls unwanted moisture away from your skin, meaning you stay dry throughout your run. The Onmi-Shade UPF 30 rating means you can run anywhere under the sun and still have an added measure of protection. This cami is antimicrobial so odor won't rule your run, and the slim style gives you a comfortable fit so you focus on more important things, like smashing your PR.
