Columbia Men's Insight Ice Short Sleeve Crew, Compass Blue, XX-Large
Airflow is just the beginning.  While built-in UPF 15 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). Gusset detail provides maximum mobility.
