Wonderful keychain, quite high quality with a good length, overall lightweight but the ball is quite heavy, you can "feel" it if necessary. It doesn't bother in the pocket and I have 6 keys and a whistle on it. Even on the motorcycle, when I have the keys in my pocket, I don't feel them unless I wear very tight pants. With the cargo tactical pants that I wear daily, I don't even realize they are in my pocket.
