Will keep you warm no matter what!

  • Familiarity: I've used it several times
  • Fit: True to size

I ordered these for a trek in the Himalayas (10k ft, -20 to 20F temps). Just trying them on in my house the first time, I ripped apart the cinch cord on one of the gaiters. Backcountry replaced it with new pair which has held up after a dozen wears. The gloves are extremely warm, but not wonderful at breathing. Make sure you have liners on to help keep your hands dry.

The 'liner' in these gloves is pretty awful. I can't imagine a situation where I would actually take the liner out after trying several times. It's hard to take out and hard to put back in. And, with only 1 finger, doesn't offer a lot of extra usability.

Overall, I'm very happy with them and would buy again.

Has anyone used these at -20 and under? I live in an extremely cold area with a lot of wind, but I don't want to pay over $150 for mitts if possible, thoughts?

Is the Shell Waterproof at all? It says the liner is the part that has the waterproof membrane, so is the shell simply for durability?

Responded on

Hi Luke,
The outer shell is water resistant but the waterproofing does come from the BDry liner. It is the blueish looking membrane in the first detail picture at the top.

Warm gloves at an attractive price

  • Familiarity: I've put it through the wringer

I HIGHLY recommend these gloves for anyone skiing the cold winters in the mountains. Living in Utah, the temperature will consistently be 0-15 degrees on the mountain. These are the only gloves I've ever had that I've sweat in 20+ degrees. Taking the liners out does not really help. The shell of the glove is too thin and flimsy to be used alone. Nor can you use the liners by themselves. If you get these gloves, also get a lighter pair for the early and late season. When I wore these in the spring, I often found myself taking them off and on because of the amount I was sweating. The liner also tends to get stuck if you soak them with sweat. However, they are designed to be used in the coldest weather and they're the best super cold weather gloves I could find. I always have worn a medium in gloves, and I do with these. They fit true to size, and Black Diamond is a great brand to buy from.

Warm? More like hot.

So warm, the word warm does not even cover it. Have had these things out East Coast skiing and climbing down to around 0 F over the last 2 years and my hands stayed nice and toasty. Only downside to this is that if it is above 15-20F, my hands sweat like mad and these usually end up in the pack as a back up. You can pull the liners out, but the shells are pretty thin, they will barely cut it for those 20F and up days skiing but I wish the shells had a little more beef to make these things more versatile. Would be nice if the shell and not the liner were waterproof. Also have never found a use for the trigger finger in the liner, I usually just jam all my fingers into the main "glove" area. In addition, for me the drawcord is on the "wrong" side, would prefer to have it on the thumb side rather than the pinkie side for easier use, obviously a small point though. Overall a (too?) warm mitten for the chilliest days. Maybe I need to move somewhere colder to fully appreciate them.

Black Diamond Mercury Mitts

  • Gender: Male

These are the best gloves or mittens I have ever owned. They are warm, comfortable, waterproof, and breathable. I recently used these on a 0 degree day with the wind blowing at 30+ miles per hour. My hands stayed toasty warm for the most part. I could not even feel the coldest gusts of wind. There was a time on the lift near the summit where my trigger finger (the liner is a three finger mitten) got slightly cold, but nothing that bad. I could just move that finger in with the rest of them. They are rated from -20-0 degrees Fahrenheit, and this is probably true if you are talking about windchill. I was not wearing a liner that day. I think I would be correct with a liner.

My fingers also stayed dry the entire day. These wick moisture very well . I used to my fingers getting wet and clammy during even the coldest day, which only added to the cold, however this doesn't happen with these mitts. my hands stayed dry, and therefore warm.

I can personally say these a very waterproof. I tested them in my sink by letting the water run onto them. I was waterproof until I tried to run the water on the nose wipe on the thumb. It got soaked, and leaked into the mitten. I personally don't like this feature. It is not soft. I would rather wipe my nose on the shell of the mitt than the nose wipe.

All and all this is about a 4.5 star mitt, but I rounded up. I wish the removable liner was a mitten because it would make it warmer. I like the versatility. for extremely warm and wet spring skiing I can wear the shell and a liner glove. The shell is not comfortable to wear alone. I the high 20s and 30s I can wear a fleece glove and the shell. Between about 5 and 25 I can wear the shell and the removable liner, and lower than that I can wear a liner glove, the removable liner, and the shell. Great mitten! Don't think you can wear these under a jacket though. It doesn't work. I love the strap that wraps around your wrist. These mittens fit large.

Awesome Mittens

  • Gender: Male
  • Familiarity: I've put it through the wringer

When I first used these on Mt. Washington in the winter, I thought they provide the same warmth as my REI swithback gloves (which is a good pair, just leaks under extreme condition). But when I took the Mercuty mittens to Mt.Rainier in blizzard condition in May, they proved to be waterproof (withou the Goretex) and very warm, after a tired day fighting with blizzard when I took these out of my pack, they were warm and remained dry. They are actually too warm for Mt. Rainier. I'd highly recommend these.

cold tips

  • Gender: Male
  • Familiarity: I've put it through the wringer

Normally the mittens are good, but on the really cold days i have been a bit dissapointed at longer belays. when the temps frop to low single digits F i have found that the very tips of my fingers get really cold. Seems like the insulation is mostly on the palm and back and the tip where they meet is a a touch thin.
I also feel they are pretty tricky to tie knots in and work biners, compared to some more snug mittens i have owned.

Check Sizing

I am 6'2 and just figured I'd be a (M) size. They are huge. Looking at the size chart im at the upper end of the (S) size. I bought them to throw in my ski bag for the days the temp drops. They would be perfect if they were not almost comically huge. ***Let me restate this...regardless that I should probably be in a size small, these gloves have far more volume then any other glove or mitten I have used.

Ryan - height doesn't correlate with hand size. Your logic has HOLES!

Responded on

A+ on this one. You can spend $300 and your hands won't be as warm. For the money this is excellent! Oh yea but buy your size it helps !!!

I bought these gloves because I was tired of cold hands when belaying and snowboarding in VERY cold conditions. These babies did the trick! I first used them while boarding at Loveland Ski area in Colorado...the temp outside was 3 degrees and the windchill was -18 degrees, despite that my hands stayed perfectly warm, even on the lift!! I've also used them for ice climbing(while belaying) and they work great as well. Great warm glove for a great price! Thank you Black Diamond.

Warm-verisitle glove

The Black Diamond Mercury mitten is my go to mitten when the mercury drops. They are extremely warm and I believe warmer and more dexterous than the Marmot Expedition glove that I have owned also. I really like the removable liner as it allows them to dry much easier making it not only a good ski mitten but a good mountaineering mitten. The mitten is also more waterproof than the Marmot Expedition one. Overall this is the Mitten you are looking for.

These are very warm. I went from wearing Kinco brand work gloves to rocking these when it's a touch cold out. Absolutely love them. I pulled out a cinch cord, but I live at Alta Ski Resort and was able to bring them to Black Diamond's warranty department at their retail store in Salt Lake and they replaced that no problem.

Great all around mitten in my opinion. Cannot really say anything bad about their waterproofness, but also should mention I've never had them in really wet conditions.

Bought on end of season sale....

I rate 5* because I love the mittens. They are not 5* perfect. The problem is that the waterproofing is in the liner. If the waterproofing were in the shell, you could wear the liner over fleece gloves or mittens and have an all temperature ski glove. On a 20 degree day, these are going to make your hands sweat.

I have Guide Gloves and hoped these would cover the warmer days, but the two are very comparable because the Mercurys are mittens. I guess the search continues for a glove for those over 10 degree days.

Anyone know how this compares to the Hestra...

Anyone know how this compares to the Hestra Heli Mitten ( I am looking for the warmest and longest lasting mitten to keep my VERY cold hands warm. I love to ski but my biggest obstacle is keeping my fingers toasty. Or does anyone have any other recommendations for warm mitts?

Responded on

I posted the answer to this question on your other question, linked to the Hestra Heli Mitten.

Backcountry ridin with my AMAZING mercury was -5 degree windchill, stayed warm all day!

Great mitts

Coldest days in northern VT, NH, NY, and now CO don't stand a chance. I bought an extra pair 3 years ago and they still have the tags on them. Sure, I take care of them, but I definitely wear them too. Great product for a great price.

Best gloves ever!!

These are the most well made, warm and water proof gloves I have ever used in my 22 years of winter mountain sports. Worth every penny. 'Nuff said.

Super Warm Mitten

Love these things! good solid construction....just like every other piece of Black Diamond gear I've ever owned.

good for cold conditions

Warmest mitten I've ever tried and my hands get cold very easily. These mitts are great for cold - very cold conditions (<20 F). The removable insulated liner dries fast so your not putting on a wet mitt the next day back on the slopes. The "trigger finger" in the liner takes some getting used to but does seem to increase dexterity (I can buckle my ski boots with the mitts on). Black Diamond has given me great customer service in the past and stands behind their product.
