One of Iceland’s more unusual traditions is to leave infants outside in their strollers to sleep in the fresh air. Tucked into fur-lined stroller bags, they rest cozy and warm inside. The Sölvhóll stroller bag is a very modern take on this age-old tradition. The inner layer is made of soft Icelandic shearling, providing warmth and comfort for the baby. The outer layer is made of a functional three-layer waterproof fabric with taped seams, creating a highly insulated barrier to the cold air around the stroller. Shell fabric: 100% Polyester.
