The ATHENA MITTEN II is made of sheepskin with diamond smock leather protection on exposed areas and features a leather palm. The high quality water-repellent and breathable padding insulation from PrimaloftA?, complemented with a comfortable soft polar fleece lining, will provide comfortable warmth in harsh weather conditions. Hipora inserts round up the protection with a microporous membrane that wicks the moisture away from the skin while blocking water penetration from the exterior.
