The Columbia Mens Zero Rules T-shirt with advanced Omni-Freeze Zero™ technology helps you stay cool on the hottest summer days.
Columbia's Omni-Freeze Zero™ technology is sweat-activated and actually cools the shirt when moisture hits the surface to help you stay at your optimum temperature on hot days while the stretch fabric allows you to move comfortably whatever you're doing. And with a UPF 50+ rating, it also provides excellent protection against harmful UV rays.
The Zero Rules Tee also features Columbia's Omni-Wick™ technology which pulls moisture away your skin for quick evaporation so you stay comfortable on hot days and it is finished off with an antimicrobial treatment to help reduce odors.
