Columbia Men's Insight Ice Mesh Short Sleeve Crew

Airflow is just the beginning. Strategic venting teams up with deftly placed blocks of pointelle mesh for maximum breathability where you need it most. While built-in UPF 50 sun protection is shielding you from harmful rays, the Omni-Freeze ICE advanced cooling technology uses your sweat to trigger a chemical reaction that actively lowers the temperature of the fabric, cooling you down in the process. Quick-wicking fabric ensures that you stay dry and comfortable by pulling moisture away from your skin and into the fabric (where ICE technology can do it's thing). Antimicrobial treatment ensures that this stays fresh and clean through the rigors of your toughest training plans.
