Thanks to this kids' base-layer set your little one can stay active in any weather. The Thermolite® material keeps children warm and dry because it transports moisture effectively from the skin to the outer layers. The set feels super comfortable against the skin and the flat-lock seams are lightweight and don't chafe. The longer, curved back hem provides extra coverage and protection and the elasticated waist makes sure of a snug fit. With this kids' thermal set, your little one has the ideal outfit when combined with a warm fleece mid-layer and functional outerwear.

Breathability level is meant to measure fabrics that are functional: meaning they keep water out, yet allow moisture to be transferred to outer layers. Breathability can be measured by different standards. Breathability is measured in grams per square meter per day, or g/m2/24h. We use our own method to determine the breathability of our products, which is comparable to the ISO 15496 standard.
