Description

Expedition-grade mitt system to slay the towering peaks, giant crevasses, and monster glaciers on your bucket list.

When the temperature outside is so brutal that your pee crystallizes before it hits the ground, the time has come to bust out your Outdoor Research Men’s Alti Mitten and its Gore-Tex shell. Constructed for high-alpine mountaineering, arctic expeditions, and other pursuits into the frigid kryosphere, the Alti Mitten blends waterproof Gore-Tex membrane with a removable PrimaLoft-insulated liner to provide digit-saving protection from the ungodly cold elements.
  • Gore-Tex waterproof and breathable membrane is guaranteed to keep you dry in brutal storms and allows evaporating sweat to pass through as you work up a sweat
  • Hefty doses of PrimaLoft One insulation traps in warmth and shields your hand from temps as low as -40 F.
  • A tough leather palm grips your poles or ice axe, and the pile fleece lining wicks moisture and adds extra comfort.
  • Updated thumb articulation improves dexterity
  • KEVLAR® stitching along the palm adds durability
  • Long gauntlet locks out snow, wind, and cold
  • Hand-warmer pocket keeps your heat pack close to your hand when the temperature really drops

Can you guess what finger I am holding up? These wouldn't be the best if you are a person who likes to express yourself with finger gestures. I am amazed how warm they keep your hands. They aren't that thick, but they sure do the trick. I don't feel I have been in extreme enough conditions to really put them to the test. Yet.

I have Reynaud's, which means my fingers loose circulation when it's cold out, and go numb. It's painful and irritating. So I'm always looking for warm gloves.

If my fingers get wet when it's cold out, it's goodnight feeling. So my gloves have to be warm AND waterproof.

The AltiMitten does the trick. With the removable liner, you have adjustment options to accommodate a wide array of weather conditions. The Goretex outer shell is waterproof--and I mean WATERPROOF. IT's great. Truly great. The inner glove is roasty-toasty warm.

I would not recommend using the inner liner by itself...it is not built heavily enough to use solo. But as a combination, or with the outer shell alone, they're great.

After some hard days skiing and hiking, they've held up incredibly well--no signs of wear or tear. And my fingers are thankful for the warmth. Sizing is true to the listing above...measure twice, buy once.

Also of note...the mittens are open inside...there are no finger dividers. I strongly prefer the open design, as it helps my fingers stay together and stay warmer.

Outdoor Research® Climbing Ambassador Shingo Ohkawa shares why he loves the Outdoor Research® Alti Gloves™ and Alti Mitts™. These expedition-grade mitts are built for winter mountaineering and ice climbing. Lightweight, waterproof GORE-TEX® protects from the most brutal conditions while keeping weight and bulk to a minimum. Moonlite Pile fleece and PrimaLoft® One synthetic insulation keep your hands warm on 8000m peaks, and Pittards® leather palms and Kevlar stitching weather the punishment of major climbs.

These mitts truly are worth the money and you will notice the first time you have them in a cold weather situation. I don't do any climbing, so I can't testify to the durability, but the palms are made of leather. They also fit true to size with the liner, if you take the liner out they will be a little big, but that is expected.

I mainly use these when I won't be moving a lot in the cold, i.e. ice fishing and dog sledding. Once you start moving, your hands will begin to sweat with the provided mitt liner. To counter this I take out the mitt liner provided and put in a lighter weight fleece glove and that works great.

The only time my hands got cold with these mitts on was sitting out on the ice (not moving) with 40mph winds in 0 degree F temps. They weren't a frost-bitten cold, but still cold enough to restrict dexterity.

All in all, this is a great mitt from a great brand! I would recommend.

Note: I have the 2009 model

I was looking for a very warm mitten for use in the high mountains, and was having a hard time figuring out which models/brands were REALLY toasty. I went to the 'recommended gear' sections of a couple guiding services (Whittaker, Alpine Ascents) figuring that they'd have a good read on it. Both had the OR Alti Mitten on the list and AAI had the Masherbrum too. So I got the OR Alti Mitten and the MtnHard Mashrbrum and tried them both out. First, the Alti Mitt is notably lighter than the Masherbrum. Both had a leather palm, but the leather on the back of the Masherbrum clearly added weight. The Masherbrum also had a thicker liner. While I haven't taken these into the cold yet, it was that perception of the Masherbrum as a warmer mitten that got me most of the way to a decision.

Fit was similar, though there was more room in the Alti Mitt. I wear size M, and my hand measures 3.5 inches across at the widest point. With the OR mitten, I had a bit more room for a liner. With the Masherbrum, I think I could have a silk-weight glove inside, but nothing thicker. Another note on fit: the thumb on the Alti Mitt was too long for me, and I can easily imagine that the consequent loss of dexterity would be a negative.

While the Alti Mitt doesn't have a large series of liners that work with it similar to the Firebrand, the Alti will be warmer. Also, in comparison to the Firebrand Mitt, you'll have a better dexterity--the Firebrand tends to be bulky to accommodate so many different liners that they tend to be less dexterous...

Bought these for a camping trip to VT to hike the long trail.. Got there on the coldest day of the year so far.. Temps were -27 with a wind chill of -56... These mitts are by far THE BEST period.. Hands were toasty warm for every second of the trip!! The removable liners are perfect for tasks that require some dexterity and the outers are strong as steel.. Would definetly recommend to everybody..

I have tested these at Mt washington in Dec on a night climb .
The temp was around 0 with a wind of 70 - mph. Every part of my body felt like it was going to fall off . I had on gloves with liners but 5 mins into the climb my
fingers were blocks of ice . I put these on and in about 20 mins I had the feeling back in the hands. If you get cold hands or just looking for plain old survival mitts
these are the best I have ever tried AND tested .
