Jmortimer, I can assure you that wearing one is decidedly not comfortable, though you do get used to it after a while. In hot, humid environments, they can be downright intolerable...but then again, being hot and sweaty beats assuming room temperature! Like Clint says about concealed guns, "It's not meant to be comfortable, it's meant to be comforting." I think the same logic applies here. Thanks for posting.
