Hot, humid conditions sap intensity and endurance precisely during those moments where your will to push on weakens. Polyester and other “breathable” fabrics passively wick away moisture to keep you from boiling over, but Columbia Omni-Freeze ZERO goes a step further by producing a cooling sensation when exposed to sweat and moisture. It’s made possible by polymer-filled, cooling blue rings embedded in the fabric that actually swell like goose bumps when you sweat, lowering the temperature of the shirt.
