Black Diamond is known for many product types, and their gloves are highly appraised. The Black Diamond collection includes several types of liner gloves designed to be worn under shell mittensand this model is the heaviest and warmest of them all. The Heavyweight Wool Liners, available for both men and women, feature reinforcements on the palm and touchscreen-compatible material on the tip of the thumb and index finger. The material blend traps the heat your body produces, while the addition of merino wool keeps the gloves comfortable even when slightly damp. Wear the Heavyweight Wool Liners on their own in cool weather, or combine them with shell mittens in colder conditions!
