I use Glads. They are amazing. They broke in really nicely. I got hit in the thumb many times in my 2 years with them and the worse I got was a little bleeding. Nothing big. They do not restict movement either. I would definetly get them. I do not think they make them any more or mabey you can only get them from a few places.
any gloves will do just make sure they have some padding near thumbs-
i used macs and sf's also ic an make goalie thumbs so i just use them for extra protection-
