The Outdoor Research Alti II Mitts are built for the harshest environments on Earth, making them the ultimate defense for skiers dealing with severe Raynaud’s, extreme high-altitude cold, or sub-zero arctic expeditions. Where standard resort gloves focus on style and buckle manipulation, the Alti II is engineered strictly around survival-level thermal retention and total protection against driving blizzards and brutal wind chill. This two-piece modular system features an ultralight, bombproof Gore-Tex hardshell mitt backed by Pittards Armortan leather across the palm for abrasion resistance in freezing conditions. Inside sits a heavily insulated, removable inner mitten packed with high-grade PrimaLoft Gold synthetic insulation. The modular nature allows you to wear the shell alone during wet, moderate ascents, use the insulated liner around the hut, or combine both for an impenetrable thermal fortress when temperatures plummet far below freezing. The obvious compromise is dexterity. The Alti II is exceptionally large, bulky, and provides virtually zero fine-finger articulation; simple tasks like adjusting goggle straps or handling zippers become deliberate chores. It is completely excessive for typical 25-degree resort days, but for skiers who simply cannot stay warm in conventional handwear, it provides near-unbeatable thermal insurance. **Highlights** - Heavy-duty Gore-Tex waterproof, breathable hardshell outer mitt - Removable inner mitt packed with high-loft PrimaLoft Gold insulation - Premium Pittards Armortan leather palm designed to resist severe abrasion - Extended gauntlet coverage with dual drawcord closures to seal out spindrift - Modular system allows independent use of shell or insulated liner **Watch-outs** - Extreme bulk makes fine motor tasks almost impossible - Considerably over-insulated for moderate or standard winter temperatures - Premium price point aimed primarily at extreme cold and alpine expeditions

The Outdoor Research Alti II Mitts are engineered for environments where standard cold-weather gear fails. Originally developed for high-altitude mountaineering and polar expeditions, this heavy-duty handwear system has earned a dedicated following among skiers who battle severe circulation issues like Raynaud's syndrome, as well as those braving deep sub-zero backcountry tours. Rather than balancing warmth with nimble hand movements, the Alti II commits entirely to absolute thermal preservation. At the core of the Alti II is a modular two-piece build consisting of a weather-shedding outer shell and a thick, removable insulated liner mitt. The outer mitt uses a waterproof Gore-Tex membrane reinforced with high-grade Pittards Armortan leather across the palm, providing an impenetrable barrier against wind, wet snow, and physical abrasion. Inside, the liner is packed with high-loft PrimaLoft Gold synthetic insulation, ensuring reliable heat retention even if internal moisture accumulates during heavy exertion. This uncompromising focus on warmth creates predictable trade-offs. The mitts are enormous, heavy, and offer virtually no fine motor control. Simple adjustments—like zipping a jacket, buckling a ski boot, or navigating a smartphone—require removing the shell or liner entirely. For typical resort days in moderate winter temperatures, the Alti II is excessive and cumbersome. For skiers facing genuine frostbite risks or severe chronic cold hands, however, it remains an indispensable piece of protective equipment.
Purpose and Target User
The Alti II Mitts target a very specific segment of winter sports enthusiasts: individuals who cannot generate or retain hand warmth through standard means. Skiers with Raynaud's syndrome, severe circulation deficits, or those undertaking mid-winter expeditions in arctic climates frequently find conventional ski gloves inadequate. In temperatures plummeting well below zero degrees Fahrenheit, standard handwear often leads to numbness, pain, or frostbite. The Alti II operates primarily as safety gear rather than casual winter clothing. While weekend resort skiers carving turns in mild 25-degree weather will find these mitts stifling and unnecessarily heavy, users facing persistent peripheral numbness will appreciate the fortress-like heat retention. It is built to keep hands functional when lesser designs fail entirely.
Materials and Outer Shell
Outdoor Research constructed the outer shell to withstand severe mountain weather and heavy physical abuse. The exterior relies on a fully taped Gore-Tex membrane that blocks biting winds and driving sleet without trapping evaporated sweat. High-stress contact points along the palm and fingers are wrapped in Pittards Armortan leather. This specialized hide undergoes an engineered tanning process that strengthens the leather fibrils, dramatically increasing resistance to abrasion from ski poles, rope friction, and sharp ski edges. The extended gauntlet reaches high up the forearm, secured by an elastic wrist cinch and an oversized barrel-lock drawcord at the hem. These closures ensure that deep spindrift and windblown snow cannot infiltrate the interior, even during falls in bottomless powder.
Insulation and Modularity
Thermal efficiency is driven by a completely removable inner mitten insulated with PrimaLoft Gold. This premium synthetic insulation mimics down by trapping warm air in tiny micro-pockets, but it retains the critical ability to insulate even when exposed to condensation or sweat. Because the system is modular, users can customize their layering setup based on immediate conditions. During high-output skinning or snowshoeing, the outer shell can be worn alone or paired with a thin liner glove to prevent overheating. In base camps or ski huts, the insulated liner functions as a standalone camp mitt. Furthermore, separating the shell from the liner at the end of the day drastically reduces drying times, a vital feature on multi-day winter tours where damp gloves can freeze solid overnight.
Dexterity and Usability Limits
The primary drawback of the Alti II is its complete lack of dexterity. With all fingers bundled together inside thick layers of synthetic loft and rigid leather, hand articulation is reduced to a blunt claw. Basic tasks like operating a ski pack buckle, opening pockets, or adjusting goggle straps require deliberate effort, while finer motor skills—such as adjusting binding screws or operating car keys—are impossible without pulling the mitts off. The sheer size of the mittens also impacts ski pole grip; skiers may need to lengthen their pole straps significantly to fit the thick gauntlet through. Outdoor Research includes removable idiot cords (wrist leashes), allowing you to safely slip the shells off during quick tasks on the chairlift or ridge without the risk of dropping them down the mountain.
Durability and Field Lifespan
Given its expedition pedigree, the Alti II is built to survive seasons of severe punishment. The heavy-denier face fabric on the back of the hand resists snagging on tree branches and sharp ice crust, while the reinforced leather palm handles repetitive pole-planting stress without premature thinning or seam blowouts. Unlike single-piece gloves that must be discarded when internal insulation packs out or lining fabrics tear, the modular liner can be repaired, replaced, or carefully washed without compromising the waterproof shell. The hardware, including heavy plastic cord locks and durable nylon webbing, is scaled up to handle frozen conditions and rough use while wearing other layers. For skiers who only pull them out on extreme weather days, the Alti II can easily last a decade or longer.
Comparison and Value Trade-Offs
At this price tier, the Alti II competes directly with high-end mountaineering mittens such as the Black Diamond Absolute Mitt. The Black Diamond option offers similar extreme-weather warmth, but the Alti II remains distinct due to its balance of PrimaLoft Gold insulation and Pittards leather durability. Compared to heavy-duty resort mittens like the Hestra Army Leather Extreme, the Alti II is warmer, far bulkier, and less naturally contoured for standard pole holding. At roughly double the price of standard ski gloves, the investment only makes sense if you genuinely need arctic-level thermal protection. Buyers seeking a versatile resort daily driver will be ill-served by its excessive mass, but for deep cold protection, few alternatives on the market can match its reliability.
How we picked
We started with a long list of ski gloves that people actually buy, cut anything that could not clear our baseline for durability and field performance, then ranked the 10 that were left against the same criteria.
