A warm t-shirt with long sleeves in 100% soft merino wool is the perfect base layer, keeping the kids warm and dry when it is cold outside. The best way to dress our children is to dress in layers: The outer layer should be durable, wind and rainproof. We recommend soft, natural, and hypoallergenic fabrics for the inner layer – especially if the material touches the child’s skin directly. Merino is one of these materials, the king of natural functional fabrics. The merino used for this t-shirt is of the superfine quality: 16.5 microns. It is a warmer version of the Merino fabric, 220g/m2, ideal for the colder period of the year.
Growing t-shirt, what size to choose? 
The t-shirt can grow with your child; the hemlines on the sleeves are 5 cm long and, therefore, can be prolonged up to two more sizes. It is unnecessary to fold the sleeves; the hemlines hold the sleeves in their space. The length is true to the most significant size, for example, 86-92/98. The t-shirt length is below the buttocks and will gradually grow with your child up to the approximately middle of the buttocks. Please order the size your child currently uses; there is no need to order the bigger size to keep using it longer.
