The soft flexible palm is made of goatskin to give the durability and ruggedness needed in an outdoor mitt.

Perfect for those with poor hand circulation and low blood pressure because they are filled with warm and lightweight down filler, these mittens are some of the best you will find on the market. Many comments can be found by happy buyers who love this product because of the comfort, flexibility, and style. People that must work in the snow either have to settle for working with numb hands and fingers or keep trying to find something to wear on their hands that will protect them even in below zero temperatures. The Mercury Mitts will do just that. They are warm even in temperatures that mittens are not normally warm. Customers with usually cold hands all winter long outdoors said they were very warm with these mittens on, allowing them to do their work comfortably and endure the freezing temperatures in their areas.


Rugged and made to last, these Black Diamond Mitts have a four-way stretch outer shell of Pretext Shield. This allows much movement for what you need to do in the snow with the dependability and long-lasting comfort that you have come to expect from this reputable company. They are resistant to abrasions and lightweight making them suitable for almost any type of activity or sport outdoors in the winter. As one satisfied customer said in his personal review of this incredible product, they are a good investment because these mitts will be in fantastic shape for years to come. The strong and high-quality materials paired with the excellent technology of their manufacturing result in a durable pair of mitts that you can depend on for many winter seasons of comfort and protection for your hands.


Several flexibility features are available with this Black Diamond item. They are roomy enough to permit the use of hand warmer packets in them for the fingers. The large gauntlets in the cuffs slip easily over the sleeve endings of jackets and coats to cut off the wind, snow, and cold air from entering the sleeves. Wrist pulls can then be tightened to ensure that the cuffs stay tight and secure. There is a good range of motion for the hands in these mittens for the many things you want and need to do outdoors. Also flexible is the liner that attaches with Velcro and can be removed for drying. It is part Velcro and part spandex to give you the versatility you desire in a mitt.

The protection of the Mercury Mitts is to keep the hands warm even in below-zero temperatures and with the liner inserted, to keep them dry. They include plenty of Primaloft insulation in them to keep hands the warmest, even in impossible temperatures. The removable liner is insulated with high-loft fleece as well, plus it includes a split-finger to increase the dexterity of the hand. You have more functional ability with this feature, but still not as much as you would with a glove. However, a glove will not keep you this warm either. That is the beauty of mittens. Manufacturers could not possibly get the amount of down that is in this mitt successfully and comfortably in a glove that has the fingers separated. Because the fingers are all together in a mitten, these products are usually much warmer for the hands. Several online buyers commented about their usually cold hands in winter being so toasty and warm in these Mercury Mitts.


The sizes of this Black Diamond item run true, according to the manufacturer and most of the customer feedback online. They are even large enough and plenty roomy to accommodate hand warmer packets in extremely cold weather and climates. The several sizes available fit well and allow the fingers the room to be balled up into a fist to increase the hand warmth inside the mitt.


The shell of these Mercury Mittens is made of nylon and spandex with a palm of goatskin. The leather palm increases the durability for hard use. it is also more flexible and pliable that another fabric would be for this section of the mitts. The waterproof lining is constructed of polyester fabric and can be used alone, as it detaches from the mitten. Made of a Pertex Shield fabric with four-way stretch and a big gauntlet, the outer shell of this product is tough and long-lasting but is not waterproof. The mitt depends on the liner for that function. The Mercury Mitt is stylish to use for outdoor winter sports, chores, and tasks that do not require the dexterity one needs from a glove.


There are so many uses for these terrific mittens that it is impossible to name them all. Most of the online customers say in their feedback that they use them for outdoor chores, tasks, and playing with the kids in the snow. Many people use them while shoveling snow because you do not need gloves with fingers for that. Any kind of outdoor task that does not require much dexterity of the fingers can be accomplished with these wonderfully warm mitts. You can use them year-round but are really only necessary for skin protection and warmth in the colder weather and northern climates. They are perfect for mountaineering, camping, hiking, and backpacking to stay warm. Any type of snow sport can be enjoyed more with these on such as snowboarding and skiing too. The possibilities are endless for using these fabulous Black Diamond mitts to protect your hands in the cold.


The only part of these mittens that is waterproof is the removable liner with the dry insert stays. The outer shell is fairly water-resistant and repellant to snow. The amazing liner gives enhanced protection from weather moisture, even if you use the liner without the outer mitten section. Using it this way would give you more flexibility and dexterity with your hand movements. This would not be advisable in extremely cold weather but could be comfortably done in normal winter climates. You would not normally submerge these mittens in snow or water, even if they were completely waterproof, so it is great that they do have some resistance to precipitation.

Ease of Use

The Mercury Mitts from Black Diamond are easy to use with the draw pulls to close them around the wrists. The gauntlets fit over any jacket or coat wrist cuffs to provide a solid barrier to the cold and wind. Use the trigger finger split in the liner for added dexterity when doing chores, tasks, or performing in sports and activities outdoors. These terrific mitts could not be any easier to use than they are. There is even a strap to attach a lanyard for when you take the gloves off and do not want to lose them. This is ideal for skiing and getting on ski lifts. You certainly do not want to drop your mitts from one of those. It is so easy to lose gloves or leave them places you go. With this attachment, you won’t misplace them anymore.

The Bottom Line

While we do agree that mitten can be bulky for some outdoor chores and activities, the Mercury Mitts do what they can to give you a great range of motion and dexterity with the split-finger in the liner. The outer material could be waterproof as the liner is to make the whole item very protective. Even so, we think that the majority of the online satisfied customers are right in saying that this Black Diamond product is quite excellent. The waterproof liner and the down filler are the features that protect the hands the most on this model. Almost anything that is filled with goose down will be the warmest and the lightest that you can find. If you suffer from cold hands all winter and could do what you need to do with mittens on, then these may just be the ideal protectors for your hands this season. Some people were hesitant to spend the extra dollars for mittens, but when they tried them on, they were glad they purchased them. For skiing, snowboarding, mountaineering, and shoveling snow, you will be warm and comfortable with these Mercury Mitts on your hands.
