What’s next to your skin sets the stage for your comfort: don’t mess around. Developed with top physiologists, Columbia’s new heavyweight baselayers offer our highest warmth-to-weight ratio for optimal comfort in extreme winter conditions.
I purchased the heavyweight base layer top and bottom to wear this winter under a heavier jacket while fishing. This weekend, I was out on the water during 40 degree temperatures with wind and rain. While my hands were very cold, my entire body under the base layer material was extremely warm. The Omni Heat technology is absolutely amazing.
