What to Wear for Tough Mudder: Indestructible Gear for Mud Races

It’s not available until February, but the Columbia Freeze Degree 1/2 Zip is a layer worth waiting for. New Omni-Freeze ZERO technology literally cools the shirt when it comes into contact with hot, moist conditions. Little blue rings embedded in the fabric contain cooling agents, that when exposed to sweat actually swell (similar to goose bumps) creating a cooling sensation around your core. As you heat up during a Tough Mudder, this is the ideal long sleeve to wear—breathable, and enough coverage to protect your skin from biting wind, cold water, and mud.
