The Columbia Boys' Baselayer Midweight 2 Tight helps keep your little guy warm while he learns to ski like the pros. Omni-Heat uses thermal reflective detailing to mirror his own body heat back to him, and Omni-Wick moves moisture away from his skin to keep him dry. That means longer days at the ski resort for you and your family. These bottoms also have an antimicrobial treatment, so wearing them two days in a row won't be a big deal.
