Aptly named after the largest lake in Lapland, often the site of frozen ice fishing, UpHillSport “Inari” Hunting H5 Socks are heavy thickness, merino wool-rich socks with a full thermal grade 5 rating. These knee length boot socks are fully terry loop cushioned to keep the ice, frost and cold out, while the breathable structure allows damp air our from the inside, keeping legs and feet warm but dry. Finnish designed and manufactured, the sock’s shaft is a flat 1 x 1 knit while the foot has a fitted heel for a wrinkle free fit and flat, smooth toe seams to prevent blisters. All UphillSport socks incorporating merino come from mulesing free farming sources.
