I have never really used mitts before but I was thinking of picking up a pair. However the size that is supposed to fit me seems too big. But then I tried on the next size smaller and found that I couldn't move my fingers around much inside the mitt. Not that I would do anything with them but it seems like it would be nice to have some wiggle room. Is that why mitts are allways sized so large? To give you room to move your fingers around inside? Should I err on the bigger side so I have wiggle room or get the smaller one so it is easier to use with poles, etc.
