The biggest thing for me is the reduced distance you get but it's not a big deal. I don't have any problem swinging, you just can't swing as full or get as much power. Depending on how many layers you have on you have to adjust your distances. Playing in a jacket over one shirt is pretty easy and I don't lose a thing. It is when you have on a t-shirt, a long sleeve t-shirt, a sweater, then a jacket, that is when the swing issues come in. The best advise is to wear larger sizes when you layer so it is looser.
