The Columbia Men's Heavyweight 1/2 zip is a great baselayer.
- Rocky Mountain Trail
When Jack Frost is relentless in his quest to keep you indoors, the Columbia Heavyweight 1/2-Zip Men's Top mocks him. This thermal base layer was constructed from two fabrics: Omni-Heat Reflective and Omni-Wick. The former uses small reflective silver dots to reflect body heat back towards your skin, keeping you warm in the process. At the same time, it also wicks excess moisture (i. e. sweat) away keeping you both warm and dry. Omni-Wick panels were inserted at the underarms and sides to increase ventilation when you're playing hard. Meanwhile, the raglan sleeves provide extra mobility, and the back hem is slightly longer in order for it to stay tucked into your bottoms. Lastly, the top is finished with a 1/2-length zipper and flatlock stitching
