Responsible Merino wool brings outstanding warmth to Arctic conditions, and lyocell adds sustainable softness. To keep children as comfortable as possible in the cold winter weather, weve learned to love layers. Especially those with wool: natural wool gives the best warmth without weight and warms you even when it's wet. Combined with moisture-managing lyocell, it's so soft and warm you could wear it all the time. The Kinsei base layer set is a great choice for the Arctic cold. Many parents choose this Reima best-seller as all-winter wear for their toddlers who don't yet run around and thus need more warmth than busily playing kids. Available from size 80 cm up until 160 cm, this kids' thermal set warms children of all ages.
