Columbia Freezer Zero II Neck Gaiter Stone Green, L/XL

It's pretty easy to focus on the fish and lose track of the sun while you're fly casting on a sparkling August river, which is why bringing the Columbia Freezer Zero Neck Gaiter is as important as bringing your tackle box. The Freezer Zero is specially woven with fibers that block all the sun's rays, and it uses Omni-Zero technology, which actively cools you down when it comes in contact with sweat.
