More than an ordinary shirt, the fast wicking Women's Zero Rules II Polo features sweat-activated cooling designed to keep you cool and dry under even the most extreme conditions. And as if that wasn't enough, it also offers UPF 30 sun protection.
Columbia was born in Portland, Oregon, USA, where snow-covered volcanos and glaciers are just a hike away. Our goal is to keep you protected no matter what. That’s why our products are tested in the harshest conditions Mother Nature can muster.
Our Tested Tough stamp is Columbia’s promise to you that we’ve done our job. We’ve tested our products high atop cascade peaks, on the crashing waves and soaking rain of the Oregon coast, and in some of the most challenging conditions around the world. All to ensure that when people wear Columbia, they’ll be able to stay Outdoors longer. And have fun while they do it.
