Ruskovilla’s silk wool garments for children are a mixture of real silk and soft merino wool. Silk wool combines the best of both of these natural fibers: it warms, breathes freely, and feels wonderfully soft against the skin. Silk wool garments are great as underwear for mid-seasons and all year round for children with sensitive skin.
70% Merino wool and 30% pure silk.
Sizes 80 - 150, based on child's total centimeter height 1 inch = 2.54 centimeters.
