Hestra says about the Heli Ski Czone Liner - 5 Finger
A waterproof liner glove in fleece with synthetic insulation and a CZone membrane stops the wet and lets moisture escape. Designed for the Hunter?s Gauntlet CZone but also fits other Hestra gloves with a detachable liner, such as the Army Leather Heli Ski. Perfect as a replacement liner if you have worn out the liner in a favourite glove or want a waterproof extra liner handy in your backpack to swap in during the day.
