Outdoor Research Alti II GORE-TEX Mitts (OR #300009)

Published · Researched 2026-09-21

2026 lineup note: Current. The Alti II GORE-TEX Mitts replaced the long-running original Alti Mitts around 2023 and remain Outdoor Research's flagship expedition mitt at $209. Offered in men's (#300009) and women's (#322152) versions with identical construction. It is OR's warmest mitt — a 70D GORE-TEX shell over a removable 340 g PrimaLoft Gold liner — aimed squarely at high-altitude, polar, and deep-winter mountaineering, not daily ski use. (Slug disclosure: drafted under provisional slug outdoor-research-alti-mitts, renamed to outdoor-research-alti-ii-gore-tex-mitts on 2026-09-21.)

Version lineage (2023–2026)

• 2010s–2022: Alti Mitts (original) — OR's classic expedition mitt: GORE-TEX shell, Pittards leather palm, PrimaLoft insulation, removable liner, long gauntlet cuff. The benchmark "8000 m / polar" mitt for a decade; discontinued in favor of the II.
• 2023–2026: Alti II GORE-TEX Mitts (current) — redesigned patterning with 170 g PrimaLoft Gold in the shell and 340 g in the removable liner (a meaningful insulation bump over the original), same Pittards Armortan leather palm, same long gauntlet. MSRP $209, unchanged through 2026.
• Still a smart buy? Used original Alti Mitts appear regularly at $80–120 and remain fully serviceable for expedition use — the liners were the wear item and are interchangeable-ish between generations by size, though OR does not guarantee cross-generation liner fit. Buy the II at retail if you need maximum warmth and the current GORE-TEX layup.

Overview

Outdoor Research (Seattle) positions the Alti II as the warmest handwear it makes — built for Denali, Aconcagua, the Antarctic plateau, and anywhere dexterity takes second place to not losing fingers. The architecture is classic expedition-mitt: a waterproof-breathable GORE-TEX shell mitt with a Pittards Armortan leather palm (grip on tools and ropes) plus a fully removable insulated liner, so you can dry the liner in your sleeping bag overnight while the shell airs. This is a bulky, low-dexterity piece of safety equipment — nobody buys it for lacing boots. Siblings in the OR handwear line: the Alti Gloves (dexterous version, less insulation) and the now-discontinued original Alti Mitts.

Key Specs

Pricing

• MSRP: $209 — Outdoor Research direct and locally.com (Sept 2026).
• Street price: Backcountry has run the mitt at $104–146 during seasonal ski-gear sales (Sept 2026, ~50% off) — worth waiting for if your expedition is months out. OR direct showed out of stock in Sept 2026 while some specialty retailers (Ascent Outdoors) showed limited stock.

In the Box

Pair of Alti II mitts with removable PrimaLoft Gold liners installed. Exact included accessories (leashes, stuff sack) UNVERIFIED from today's research — retailer listings describe the liner as included/removable but do not itemize small accessories.

Warranty

OR's Infinite Guarantee — lifetime coverage against manufacturing defects, per retailer warranty listings ("Manufacturer Warranty: lifetime"). OR's warranty reputation in the outdoor industry is excellent and repair-friendly, but extreme-expedition wear (abraded palms from ropes/tools) is the classic gray area between defect and wear.

Support & Parts

OR sells gloves/mitts direct with a strong parts culture for buckles, straps, and leashes on packs — but replacement liners are not reliably sold separately, a long-standing community complaint that carries into the II generation. If the liner packs out, you are generally buying a new pair, which matters at this price.

Community Verdict

The thin social signal is consistent: this is the mitt people buy when warmth is non-negotiable. Rokslide forum hunters call the Alti "superbly warm for late-season Alberta"; a Trailspace owner review calls the Alti line "the warmest handwear I have ever owned." The recurring counter-themes are bulk — multiple owners describe them as the warmest and least dexterous thing they own, strictly a belay/8000 m piece — and weight, with the mitt drawing criticism as a heavy addition to an already heavy kit. An Arctic-voyage review of the generation noted wishing for more palm insulation and flagged that liners are not sold separately as a real miss. No fabricated scores; community verdicts on expedition mitts are always qualitative.

Long-term durability & warranty-claim reality (enrichment — Sept 2026)

The Alti's reputation is "buy it for the one expedition, keep it for a decade of winter camping." The failure points owners report are the leather palm (abrasion from ropes, ice tools, and ski edges — expect to re-treat or eventually re-palm with heavy use) and liner loft loss after repeated stuffing, which is the bigger problem since liners are not reliably sold separately. The GORE-TEX shell itself is durable for a softgood. Warranty-claim reality: OR's Infinite Guarantee is genuinely good, but palm abrasion on an expedition mitt will almost always be classified as wear. Buy with the expectation that the liner is the lifespan limiter.

Version history — year by year (enrichment — Sept 2026)

• 2023: Alti II GORE-TEX Mitts launched, replacing the original Alti Mitts — insulation bumped to 170 g shell / 340 g liner PrimaLoft Gold, $209.
• 2024: Continued; colorway rotations (Agate, Rainforest, Black).
• 2025: Continued at $209.
• 2026: Continued at $209; no Alti III announced as of Sept 2026.

Head-to-head vs closest rivals (enrichment — Sept 2026)

• vs Black Diamond MidWeight Gloves (/library/gear/clothing-footwear/black-diamond-midweight-gloves/): not really the same category — the BD is a daily-driver softshell glove while the Alti II is expedition survival gear. You own both: Alti II for the summit push and 8000 m camps, the BD for everything below.
• Expedition-handwear coverage in this catalog is currently thin — the Alti II is the only true expedition mitt dossier as of Sept 2026. If your use is resort skiing or winter hiking rather than expeditions, you are overbuying: a standard insulated ski mitt at half the price and two-thirds the bulk is the smarter pick.
• Do not confuse with: the original Alti Mitts (used market, still excellent) and the Alti Gloves (same branding, far less insulation).

Care & maintenance (enrichment — Sept 2026)

Remove and air the liners after every use — never store them stuffed inside the damp shell. Leather palm: treat with a leather conditioner made for GORE-TEX-adjacent products (keep conditioners off the nylon shell). Re-apply DWR to the shell when water stops beading. Store uncompressed in a dry place; the 340 g liner needs loft to do its job.

Buying traps (enrichment — Sept 2026)

• Original vs II: used listings often just say "Alti Mitts." The II has the updated patterning and heavier insulation — at $80–120 used for the original vs $104–146 on sale for the II, the sale-price II is usually the better buy.
• Glove vs Mitt: OR sells "Alti Gloves" under near-identical branding. If the listing shows fingers, it's the glove — roughly half the warmth.
• Sizing: expedition mitts are sized to fit over thin liner gloves; size up if you plan to double up, and check OR's size chart rather than guessing — returns on $209 mitts are annoying.

Community Verdict — additional voices (enrichment — Sept 2026)

Additional sourced voices (Sept 2026): an Arctic-voyage reviewer praised the overall warmth but wanted more palm-side insulation and called the non-replaceable liner a miss; Rokslide's hunting community treats the Alti as the late-season standard where sitting still in extreme cold is the whole activity; Trailspace's owner review ("warmest handwear I have ever owned") is the representative superlative — and the representative caveat is always bulk. Facebook-group discussion of the Alti was not findable via public search — the social layer here is forums and owner reviews, which is typical for low-volume expedition gear. No fabricated scores.

Key Specs gap-fill (enrichment — Sept 2026)

Weights in both units: claimed men's pair weight 12.6 oz = 357 g (Ascent Outdoors); Backcountry lists a claimed 11.8 oz (335 g); OR's own current site listing has shown up to 19.36 oz (549 g) for the women's — the exact per-size/per-gender official weights are inconsistent across sources, UNVERIFIED as a single authoritative figure. The mitt is heavy either way: expect roughly 350–550 g per pair depending on size and gender. Insulation: 170 g (shell) + 340 g (liner) PrimaLoft Gold — the headline warmth spec. Shell: 70D 2L GORE-TEX. No CE/UIAA certification applies to mittens.
