Layer the Black Diamond Midweight Gridtech Liner Glove underneath your ski mittens, or wear it on its lonesome as you go for a cool weather run. Whatever your choice in activity, the Midweight features Polartec Power Grid fabric that not only provides warmth, but is highly breathable, wicks away moisture, and dries quickly. A silicone palm offers just-enough grip when you need it, and the thumb and index finger are touchscreen-compatible for your convenience.
