With a sturdy design plus well-sewn leather and synthetic construction, the Black Diamond Transition gloves are some of the most durable and comfortable gloves that we tested. They rivaled the Petzl Cordex in both comfort and durability but fell short by just a hair. We liked the stretchy synthetic backing and leather knuckle protection, which was breathable but not flimsy. 
The Transition gloves are dexterous for a full-finger model but didn't feel as dextrous or nimble as the Cordex, which are lighter and offer more finger and palm protection. The Transition gloves run small, and our lead tester, who typically wears a size medium, found a large to fit perfectly.

Review: Black Diamond Tour Gloves - FeedTheHabit.com

The Black Diamond Crag Half-Finger gloves have plenty to offer if you're looking for a lightweight model that is comfortable and breathable. They are fully synthetic and are perfect for hot weather and shorter big wall climbs. They feature two different loops for clipping onto carabiners and have a bit of padding over the knuckles, which was nice for jugging ropes. The Crag Half-Finger gloves are significantly more comfortable and breathable than their leather counterparts, which offer more protection but feel stuffy in hot conditions.
The main downside of the Crag Half-Finger is that they are not very durable for prolonged use. We used them on a few walls in Yosemite, including a one-day ascent of El Capitan, and were impressed with how well they held up after so many pitches. Even though they worked well for a few big climbs, the Crag Half-Finger gloves wear out quickly from rappelling, and we would replace them after a few months of use. They don't offer much protection while rappelling because the palms are thin and transfer a lot of the heat from rope friction. If you're looking for a heavy-duty fingerless glove, then the Metolius Climbing Glove is a full-leather option, but is also much less comfortable than the Crag Half-Finger.
