I also bought a pair a month ago. The grip on the clutch fingers came off, but that can't really be stopped. Like Crafty said, they breath well, I live in FL.
They didn't have a perfect fit for me new, so I bught a pair of larges. I kind of wish I bought mediums, like my friend has, because I am sure with the humidity down here, they would break into my size, so I have to suffer with a centimeter of play at the tips.
The price is well worth it, but if you can't afford these, Frank Thomas has a pair just like them, which another friemd of mine has, and they are about 1/2 the price. I didn't get them because the sizes different, and the palm area seemed to be more snug than the AlpineStars.
