Black Diamond Crack Gloves have it covered from hand cracks to offwidth sizes
I've used these gloves in Yosemite, Black Canyon and the Utah desert, and also crammed them into some sharp, crumbly choss cracks near my home on Colorado's Western Slope, and they're holding up well, much better than I predicted based on how thin they felt when I first tried them on. The synthetic suede has stretched a little, which is both good and bad in respective terms of comfort and performance; the thin rubber coating is starting to delaminate a wee bit from all the desperate thin-hand jamming; and the plastic-reinforced slot that the wrist strap connects to is beginning to tear (see photos). I thought the finger loops might be one of the first things to break, but those are fine so far. Considering that I've used these light, thin gloves on thousands of feet of rock and they are still holding up, I'd say they are worth the money.
