Thermal ski sock for children made with Lana Merino and with the smart Outlast® fiber, which generates a microclimate between the garment and the skin where it retains heat. It is a recommended fiber for practicing sport at height and at extreme temperatures. Knitted seamless at the toe to prevent chafing and discomfort, this sock features special channels developed by Mund Socks that improve breathability. In turn, this model has a reinforced heel and toe box to guarantee comfort and convenience during skiing, snowboarding, or any winter sport. It is a perfect garment for children to enjoy the snow and practice their favorite sport with their feet fully protected.
