I LOVE THESE MITTENS SO MUCH. I bought one pair at the beginning of winter 2014, and since then they've been my only mittens. I've washed them repeatedly and used heavily through 4 winter seasons. This morning I wore them for the first time this season and they look great, only slightly worn, no rips, no tears, and seriously still the WARMEST mittens. My fingers get very cold very fast, and I have to be careful because otherwise my fingers get extremely painful and I get miserable. But these mittens keep my fingers toasty warm, and the materials are so solid. These are really worth the money. This morning I realized in horror that I only have my one pair, and what would I do without them, so here i am 4 years later buying two more pair. I wear a medium which I decided is a little snug, so I bought a large this time. And one pair in white, because white in winter is so delicious. :-)

I always have cold hands when I'm skiing, no matter what I have worn previously. THESE are AMAZING . Not one moment of OMG my hands are cold. I purchased the Large size since I didn't want them to be too short. I have pretty average sized hands - size 6 ring, 5'8" tall, so I have no issue with the sizing.

I purchased this item for the warmth and for the wrist strap since I am forever taking my mittens off when out skiing. Originally I accidentally purchased an XS. The company was kind enough to help me return them for a medium. The MEDIUM feels SMALLER THAN THE XS!!!. I can not get my hand in and certainly there is no room for a hand warmer. Since I bought these at the start of the season and only just recently needed them for a cold snap it is too late to return. Also to try them on I had to remove the packaging so again, unable to return them. I am very disappointed in this product.I have 3 other pairs of ski mittens, all are a size medium. Perhaps the ones I got were mislabeled? I have never worn any items other than small or medium. So Sad.

These are by far the best mittens I have purchased. I wasn't crazy about the idea of spending that kind of money (what if they aren't warm, what if I don't like them). But they are great! I bought them primarily for snowshoeing and hiking. But due to the lack of snow, I have them in my car because of my long commute. They fit me fine, just a little small. I wish I would have ordered the large, but they weren't available...and still aren't. I would definitely recommend these mitts!

I purchased these gloves because I was sick and tired of my hands always being cold. I had purchased other gloves for cheaper at other well-known stores and my hands were still cold. I wondered if these were worth the money and they truly are! These gloves are simply amazing! It gets to negative 30-50 below zero where I live and these gloves have stood the test! My fingers stay nice and toasty. I have very small hands/fingers (size 5 ring) and the XS fit perfectly. You will not regret buying these gloves, worth every penny.

Marmot isn't joking around when they say this is the warmest mitten. I bought these as a gift for my sister who lives in Bend, OR and she is stoked on how warm they are. Shoveling snow and scrapping ice off the car becomes exponentially more enjoyable and say goodbye to cold hands when skiing and snowboarding.
These mittens are super waterproof and even after hours in the snow, your hands still stay toasty warm inside. My sisters says that the best feature is how breathable these are, compared to mittens she has had in the past, they stay toasty warm and not sweaty and soggy on the inside.

She especially likes how soft the mittens are and how high they go up around her wrist which makes them easy to pull up over a jacket.

Got her a small and she has small-medium hands and they fit great.

These mitts slip on easily with the help of heafty cuffs that also help keep me warm and dry. These also have a zip pocket for handwarmers but my hands have been nice and toasty so I haven't needed to use it! A great buy for the cold blooded loved one in your life!

Tested out these mittens in early January after a snowstorm in Colorado. They worked great for the slopes and kept my hands very toasty. My hands are always quick to get very cold and these mittens worked great! I like the top zipper pocket to keep the hand warmer inside so it's not bouncing around inside the mitten.

I'm not going to sugar coat it. these mittens are BIG.
Pros
- Warmest solution I have found so far
- Zippered pockets for warmers or random small objects
- Easy enough to get on with the long cord to pull at
Cons
- Not quite the super mitten I was expecting below 20 degrees: fingers still get chilly

I have horrible Raynaud's which means I'm in the ski lodge often running warm water to bring my fingers back to life. Wore these on the first ski trip and so far so good. They seem to work pretty well. The only downside is that the heat pocket is on the top of the glove and for me, I really need it under my fingertips. Great gloves so far and the medium fit best although I have pretty tiny hands.

I decided to buy these mittens after reading all the reviews from other people with Raynauds - and I'm so glad I did! Running, skiing or really doing anything outdoors during Colorado winters is difficult when you have to go inside to re-warm every 30 minutes, but these mittens totally changed that. Wore them for a long run on a blustery, 15 degree (without wind chill!) day and my hands stayed reasonably warm. They did get a little sweaty but I prefer that to frigid fingers. The lining is very nice and soft as well. I've seen some people saying these have a glove liner, but it is actually a mitten liner.

I have bad Reynauds. My ski days use to be constantly interrupted by breaks to resuscitate my fingers. With The Warmest Mittens (so appropriately named) my days on the slopes are much more fun and comfortable. I highly recommend them. The only con and why I'm giving it 4 stars is that one of the wrist straps ripped off shortly after I started wearing them, which makes pulling that mitten on a bit more difficult.

These mittens are amazing. I wore them for the first time today to test out in the brutal Chicago weather. Today's temp is 7 degrees and really really windy. My hands were the warmest part of my body. I have very small hands and the xs fit perfectly. There is not a removable liner but it's perfectly fine, the lining inside is very soft and comfortable. I wish I could find a coat this warm and windproof!

I purchased these for my wife. On days with -40 conditions, she would happily report her hands were hot and the gloves were awesome. A zip pouch for hand warmers on the back of the hand makes these adaptable to any conditions. She still wants a vacation in Hawaii for a month during winter, but I get some props for the mitten purchase.

Literally. Great for those who battle poor circulation no matter how many liners and hand warmers are used during a day of skiing. Some of the reviewers complained about the gloves getting damp, but if you have issues with staying warm in general and/or use them only on cold days, the Primaloft insulation delivers and I would highly recommend them. Also, they fit true to size and are extremely comfortable.

I don't have great circulation and my hands (and toes) are always cold skiing, no matter what I do. I finally ordered these after reading so many positive reviews, and I wore them skiing in Jackson Hole when the temps were between -11 and 4. I added my own thin glove liners since this mitten doesn't come with any (which is fine). I'm happy to report the mittens worked wonderfully and I only got a tiny bit cold, which is amazing compared to normal. If you're going to go in temps even colder than the negative single digits, I'd recommend going with the Marmot Expedition Mitt, which is one step up on the heat scale. (But those things are super super bulky--they're meant for, like, antarctic expeditions.) All in all, I'm way pleased with this purchase and this will be my go-to ski mitten for very cold days at the resort and in the backcountry. I like keeping glove liners on underneath so I can easily slip the mittens off to fiddle with my boot buckles, phone, etc.

These mittens were extremely warm for below-zero skiing in Colorado. Unfortunately, the liners did not dry completely and they were cold and uncomfortable by the end of Day 3. Problem seems to be that moisture never escapes from lining. Also, they are very thick and I always had to remove them to make boot adjustments; clumsy to put through loops on ski poles.

I was never a mitten fan, as I didn't like the lack of dexterity that accompanied them. But for my trip to the Arctic I thought they would be the warmest option. After asking around, I went with these, and was very glad I did! I must have abnormally large thumbs, because I had to get the large in order to fit them, but that left some extra room for my fingertips. Even so, they were warmer than they've ever been with gloves, even at -40. And that was just standing around. If I was moving (such as the many times we had to dig cars out of snowbanks), they were almost too warm! I didn't even use the nifty pocket for the handwarmer packs, but they're there if you want them. Expensive? Yes, but worth every penny when it comes to comfort in extreme cold.

We got these mittens for my wife. She is actually allergic to the cold but loves skiing and we have a second home up in the mountains. We got her these mittens and have had no issues since. She skis, snowshoes and wears them out on cold nights to dinner. She loves them and I would recommend them for anyone that wants super warm mittens.
