The GripGrab Liner is made as a insulation glove, to wear underneath your regular glove to provide extra warmth.

The merino wool is perfect for this purpose, as it is a great insulatior, and at the same time is extremely breathable and sweat transporting.

Even though the gloves are made to wear underneath another glove, you can still use them as they are, due to the wind and waterproof material is present.
