OMNI-FREEZE — ZERO: For heat and humidity, with activity in extreme conditions. Blue rings react with sweat to lower the temperature of the fabric so you feel cooler, while the accelerated wicking process keeps you dry and provides next-to-skin comfort. OMNI-SHADE: For mild to extreme sun exposure. Blocks harmful UVA and UVB rays that cause sunburns and long-term skin damage. Tight weave construction offers lasting sun protection with the Skin Cancer Foundation's Seal of Recommendation. OMNI-WICK: Moisture-wicking technology for the outdoors. Omni-Wick pulls moisture from the skin into the fabric where it spreads across the surface to accelerate evaporation—for fast drying, enhanced next-to-skin comfort. HANDY FEATURES: Accessory pocket on one sleeve, flatlock construction, and thumbholes. BUILT TO LAST: Columbia’s attention to detail is what sets our apparel apart. Specifying only the highest quality materials, expert stitching, and craftsmanship. This is a long-lasting garment you will enjoy for seasons to come.
