The G1 Glove Liners can be used under dry gloves or wet mitts. The 1.5mm hydro foam provides the confidence that in the case of a dry glove failure, the glove liners will retain some of the thermal protection they offered when dry, and the bamboo derived fabric lining inside provides excellent thermal protection. The glove liners can be used with traditional insulate gloves in a layering system under the dry gloves for extreme conditions.
