For backcountry skiing, fully insulated gloves can cause hands to overheat on the ascent, which is why many skiers rely on liner gloves for the climb and switch to a warmer glove at the summit. The Liner Glove offers a thin, lightweight, and stretchy fleece construction that works perfectly on its own for light-duty activities—such as winter running or spring skiing—or as a warm, comfortable layer beneath heavier gloves in colder conditions.
