A light yet warm multilayer sock designed and made in Finland for younger skiers taking on fast slopes and to be worn with a hard racer ski boot. Knee-length UpHillSport “Halla Jr” Alpine Ski Pro 4-layer L3 Socks are suitable for all skill levels, and have a fitted feel, exceptionally thin in the leg shaft with a protective padded shin, a fitted heel and elastic mid-foot band to keep the sock in place without wrinkling. The 4-layer construction guarantees great breathability and moisture control while keeping the legs and feet warm to a thermal grade of 3. A terry loop cushioned sole is made using warm, natural (and mulesing free) merino wool. Smooth toe seams are used to help prevent chafing and blisters. All UphillSport socks incorporating merino come from mulesing free farming sources.
