Mountaineering mittens Black Diamond Mercury Mitts

Black Diamond Mercury Mitts - the warmest and lightest expedition gloves designed for mountaineering, skiing and hiking.
The stretch fabric shell and long glove cuff keep moisture out, while the goatskin palm and extra layer of reinforcement withstand stress on rocky terrain, repeated rope handling and general wear and tear associated with use in the mountains.
It has a reinforcement on the thumb for working with fixed slings.
The shell fabric is a durable yet lightweight, 100% recycled fabric with stretch for freedom of movement.
GTT Empel DWR is a revolutionary PFC-free water-repellent coating that offers superior performance and durability.
The removable lining includes PrimaLoft Gold insulation on the back of the hand and PrimaLoft Gold with Grip Control on the palm, while the soft recycled fleece lining provides maximum warmth and manoeuvrability.

MANUFACTURER
Black Diamond
Black Diamond is a world-famous manufacturer of equipment for mountaineering, skiing and mountain sports, based in Utah, USA, and also has an office in Innsbruck, Austria. Black Diamond is owned by Clarus Corporation, which also owns Pieps and Sierra Bullets.
The history of Black Diamond goes back to 1957 - a young climber and surfer Yvon Chouinard buys a used blacksmith's horn, a 138-pound anvil and a hammer. In his improvised forge, he begins to manually forge rock hooks, which he later sells directly from the trunk of his car, providing himself with a livelihood.
Now Black Diamond Equipment is a huge company with a turnover of 200 million dollars a year, headquartered on three continents (USA, Switzerland and China), including several reputable brands (Bibler Tent, Pieps, POC, Gregory), which are still headed by young enthusiasts of their business, continuing to raise the bar of comfort and safety while relaxing in the mountains.
Black Diamond is a great example of a socially responsible business - the company sponsors many non-profit organizations that somehow support mountain sports - American Alpine Club, The Access Fund, etc.
