The Isbjorn of Sweden Husky Sweater Baselayer starts with RWS-certified, mulesing-free wool and FSC-certified bamboo, blended into a toddler baselayer top. The wool warms, and the bamboo moves moisture away from the skin, so the blend feels warm when wet and cool when warm. It also works as a pajama sweater or cozy leisure wear. What Our Gearhead(R) Experts Are Saying:"When I pulled a jacket on over this top, the soft, stretchy fabric moved easily with my toddler's arms. The flatlock seams stayed comfortable under the sleeves all day."
