So can a fabric be able to really cool you down when the heat is up and you’re all sweaty? I never thought it would be possible but somehow the folks at Columbia Sportswear managed to pull it off with their new technology called Omni-Freeze Zero. I actually have heard about it August last year when their Columbia Ice T came out (supposed to be the first shirt that can lower body temperature) and was waiting for it to arrive in the Philippines. It took a while but finally last weekend, we were able to try the technology ourselves when we went to Corregidor Island. We were given a Columbia Freeze Degree Short Sleeve Polo Shirt to wear during our Photo Challenge and test the Omni-Freeze Zero in the harsh humid conditions of the island.
How does it cool?
The Omni-Freeze Zero is not chemical based but more on the architectural design of the fabric. The rings found under the shirt fabric are hydrophilic polymer rings and as the fabric spreads the sweat, the rings absorb the moisture and expands like a doughnut. It then uses the body heat as energy to make these rings swell. Against the skin it would make it really breathable and cool by lowering the temperature until the fabric dries out.
