Inspired by cross-country skiing on routes around Lapland’s Salla mountain, UpHill Sport “Salla” XC Skiing M4 Socks are sophisticated merino wool blend, crew length knits with cuff to toe terry loop, level 4 insulation that ideally suits the ever-changing and challenging sub-zero conditions typically encountered on long snowy terrain treks. Because cross-country activity generates a lot of body heat and perspiration, the socks’ material combination keeps heat in, while absorbing, then breathing out moisture. The socks are fast-drying and odour-resisting. The crew length leg shaft is ribbed and elasticated for hold, with an arch grip for a secure fit, and comfortable seamless toes. Finnish-designed and made, Uphill Sport seek to prevent animal cruelty by only using wool sourced from mulesing-free merino flocks.
