Summertime temperatures for winter-bound hands. The soft blend of 88% polyester and 12% spandex found in our Heavyweight Glove Liners provides unsurpassed warmth and maximum flexibility in cool to cold conditions. Wear them alone during forward-motion pursuits, or paired with a shell when the barometer falls. Soft, dexterous and snow-shedding, they're our top pick for summer alpine routes or winter skin paths.
