Alti II Mitts

Built for brutal environments where typical winter gloves fail, the Alti II Mitts are specialized tools designed for high-altitude mountaineering, polar traverses, and severe sub-zero expeditions. The modular two-part design pairs a rugged waterproof shell with a removable, high-loft insulated liner. It is explicitly engineered for surviving extreme freeze zones where preventing frostbite overrides the need for fine motor control, trading dexterity for sheer thermal defense.

The exterior utilizes a hardwearing waterproof-breathable shell reinforced with a durable leather palm to withstand rope friction, ice axe shafts, and cold metal hardware. Synthetic insulation throughout both the liner and shell ensures the system continues trapping heat even when exposed to interior sweat or spindrift, a distinct reliability advantage over down in sustained multi-day cold. Deep gauntlets fit cleanly over heavy expedition parkas and feature glove-friendly pull cords that work reliably in howling winds.

In the field, handling carabiners or adjusting crampon straps is clumsy and deliberate, which is the expected trade-off for this class of mitten. Compared to rivals like the Black Diamond Absolute Mitt, the Alti II offers an exceptionally proven balance of moisture resilience and brute-force warmth. They are bulky to pack and completely excessive for standard winter conditions, but when the mercury drops far below zero, there are few handwear systems as dependable.
