Every child on the slopes will need to have the full superman two piece base layer set! With Climate Control (avoid global warming) which is a special polyester fabric with a non-absorbent fibre construction that allows moisture to proceed through to next garment. The channels on the inside provide air circulation and create a microclimate next to the skin keeping your little darlings dry and sweat free. The top is a long sleeve crew neck with cuffed sleeves and the the pants have an elasticated waist with cuffed ankles. (Measurements displayed are from Achilles to nape of neck).
