They tore at the tips the first day I used them. Not very durable for moutaineering and climbing on rocks.
They also did not keep my hands very warm at all, in only 45-50 degrees F. I don't recommend this glove.

I really like these gloves because they fit very well (my hand is 7.5 in. long and size large fits perfect). They are great for everyday wear in not-so-frigid temps. Below 30-35 degrees i would go with something a little warmer. According to the size chart I'm a medium, but I definitely wouldn't want anything smaller than a large- you may want to go with one size up than it says on the chart.

I am a huge fan of liner gloves for backcounty skiing and winter camping, and these BD Woolweights are perhaps the best combination of features yet for my purposes. They are thick - think expedition weight (for a liner, that is) and surprisingly warm. For the uphill skin before a ski descent, I find my hands are plenty warm in these alone, in temps down to around 15 F or so. For the descent, they are usually warm enough when worn beneath a windproof shell (such as the OR Endeavor mitts). An especially nice feature is the full leather palm with a reinforcement between the thumb and forefinger. If you've ever shredded a pair of liners near the thumb by grabbing skis around their edges, you'll definitely appreciate this addition (note that it is a little difficult to see this leather strip in the picture). The wool blend fabric is not windproof (nor is it meant to be), but provides some resistance to moderate breezes while letting sweat escape. I wear a size large, and these fit true to size, albeit snugly. For a looser fit, size up. One caveat so far: after several days of use, the fabric has started to pill around the knuckles. This hasn't affected the durability yet, but it is something I'll keep an eye on.
