Glacier Mittens from Fusalp. The softshell mittens are designed for cold temperatures and are made with polar fleece lining and lightweight water-repellent and breathable insulation from Primaloft. This provides a pleasant warmth in harsh weather conditions. A sheepskin insert reinforces the palm, while Hipora inserts round out the protection with a microporous membrane that transports moisture away from the skin while blocking water penetration from the outside.
