Just what I wanted
These are heavy enough to do well in cold weather down to 40 degrees for sure. We don't much below that very often here in Houston. They have certainly served to keep my hands warm and the exposed fingers from last knuckle on each one make it possible to do work that requires fine use of fingers. I don't know enough about other varieties of the same idea (fingerless gloves), but Ii do know that these have served me exactly as I need.
