A super-cooling tech tee with stretch and sun protection, the soft and lightweight Men's Zero Rules Long Sleeve Shirt sports Columbia's industry-leading cooling technology, which reacts with your sweat to lower the material’s temperature and keep you cool during dynamic aerobic activity in the heat.
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.
