Here's what other sites are saying:
A lot of unseemly sweating takes place under the pits, which is why Swix made the Men's Polaris Turtle Neck mid-layer with mesh underarms for extra ventilation. A front zipper allows for extra cooling on the ski slopes, and the fitted cut means you can easily layer a fleece or softshell on top of this Swix turtleneck. Wicking, waffle-textured polyester takes care of moisture. Tuck the back drop-tail in for lower-back coverage.
