What Our Gearhead(R) Experts Are Saying:"The split-finger design is the right answer when you need to operate gear in serious cold. You get the warmth of a mitten across the finger mass while still being able to pinch a buckle or work a zipper when it counts. The GORE-TEX insert with Plus Warm Technology keeps moisture fully out, the removable liner with Primaloft Gold and boiled wool adds a meaningful warmth layer, and the large gauntlet seals the wrist properly. These have been in serious mountaineers' kits for years for a reason. Size up if you plan to wear a liner glove underneath."There are gloves built for cold days and there are gloves built for the kind of cold that ends a trip. The Black Diamond Guide Finger Gloves sit firmly in the second category. The split-finger design combines ring and pinky fingers on one side and index and middle on the other, grouping warmth where the body generates it most efficiently while keeping enough separation to work a carabiner, adjust a binding, or manage a rope without pulling the glove off. That is the compromise a full mitten cannot make and a standard glove cannot match. A GORE-TEX insert with Plus Warm Technology provides total waterproof and breathable moisture protection from the outside, while the removable liner combines Primaloft Gold insulation with a boiled wool blend backhand for warmth that stays consistent through a full day in serious conditions. The goat leather palm and reinforced palm patch handle the abrasion of rope, poles, and ice tools without wearing through, and foam padding on the knuckles takes the edge off impact. A large gauntlet closes out powder and cold air at the wrist, and a suede leather nose wipe on the thumb handles the practical realities of a hard charging day. These are the gloves that come back out of the pack every expedition.
