It may officially be rated a midweight shirt, but the Columbia Boys' Baselayer Midweight Mock Neck Top boasts some heavyweight warming power. The Omni-Heat thermal reflective technology on the inside means that this top does a lot more than just put another layer between your young outdoorsman and the cold.
- Omni-Heat thermal reflective dots reflect body heat back for extra warmth, but still allow fabric to breathe to prevent overheating
- Omni-Wick treatment boosts wicking power so he's not out in the cold in soggy underlayers
- Touch of stretch and gusseted underarm construction give him all the mobility he needs on the slopes or in the back yard
