The original Polarmax thermal — and still the one everything else is built around. Single jersey knit with slight brushing delivers a soft, lived-in feel that kids actually want to wear, while Acclimate Dry polyester fibers work continuously to transport moisture away from the skin, keeping them warm and dry through active play and changing conditions.

The relaxed fit moves naturally with growing bodies and layers easily under a jacket or snowsuit without adding bulk — reliable everyday warmth without overthinking it.
