Fourth Element G1 Glove Liners can be used under drygloves or wet mitts. Constructed with 1.5mm hydrofoam to ensure confidence that, in the case of a dryglove failure, Fourth Element G1 Glove Liners will provide some of the thermal protection they offered when dry and the fabric lining inside provides excellent thermal protection. Fourth Element G1 Glove Liners can also be used with traditional Thinsulate gloves in a layering system under drygloves for extreme cold conditions.
