Full Review

The Black Diamond Mercury Mitten Gloves are designed for climbers and winter sports enthusiasts seeking robust hand protection in extreme cold conditions. These mittens boast a versatile and innovative design that combines the warmth of a mitt with the dexterity of a glove. Featuring PrimaLoft Gold insulation and a waterproof, breathable BD.dry insert, they ensure your hands stay warm and dry during prolonged exposure to snow and ice. The durable nylon shell and goat leather palm provide excellent grip and abrasion resistance, making them ideal for technical climbing or alpine adventures.

What sets the Mercury apart is its removable liner, which allows for customization of warmth and ease of drying. The mitten shell includes a hook-and-loop wrist closure and a gauntlet with an adjustable cinch for a secure fit and snow protection. Additionally, the gloves come with a carabiner clip for convenient attachment to your gear. While these mittens excel in insulation and weatherproofing, their bulkier profile may impact fine motor tasks, though the liner can help alleviate this to some extent.

Overall, the Black Diamond Mercury Mittens are a premium choice for those needing exceptional warmth and durability on demanding cold-weather expeditions. Their blend of materials and thoughtful features make them a reliable companion for alpine climbing, ski touring, and cold-weather hiking.

Warm and Durable Mittens for Alpine Climbs
I took these mittens on a week-long climbing trip in the Rockies, and they kept my hands warm and dry throughout. The removable liner is a great feature, allowing me to adjust the insulation as needed. The leather palm provides excellent grip on ropes and ice tools.

Great Warmth but a Bit Bulky
These mittens are incredibly warm and waterproof, perfect for cold conditions. However, the bulk makes some tasks like adjusting gear a little tricky. The liner helps somewhat, but if you need fine dexterity, consider this limitation.
