I always wear gloves when I shoot my bow, even if it 90 degrees out.
I started using batting and golf gloves a few years ago, and I love them. The sued (sp?) type seems to keep you a little warmer, but even in hot weather our bow hand will not slide on the grip from sweat. They are tight enough that they don't cause any problems getting hung-up or anything either.

P.S. I shoot a release.
