The Outdoor Research Alti II Mitts represent the pinnacle of cold-weather hand protection, specifically engineered for extreme conditions where conventional gloves fall short. The double-mitten construction combines an outer Gore-Tex shell with a water-resistant liner mitten that can be worn separately or together, providing exceptional versatility across varying temperature ranges. With 340 grams of PrimaLoft insulation in the shell and an additional 170 grams in the liner, these mittens create an insulating barrier that maintains warmth even in temperatures plunging to -50°F. The Gore-Tex membrane ensures complete waterproof protection while allowing breathability to prevent moisture buildup from perspiration.
The extended gauntlet design reaches mid-forearm, creating a seamless transition with jacket sleeves to eliminate cold spots and snow intrusion. Users with circulation issues like Raynaud's syndrome report these mittens provide reliable warmth where other options fail. The SuperCinch closure system and elastic cuff create a secure seal around the wrist, while the velcro connection between liner and shell ensures components stay properly aligned during activity. Though the premium materials and construction command a higher investment, the Alti II Mitts deliver uncompromising performance for winter mountaineering, arctic expeditions, or anyone requiring maximum hand protection in severe conditions.
