I'm not writing this on behalf of myself, but on behalf of my son, who has worn many different mouthpieces. He has stated many times this was his favorite kind "due to the large opening in the mouthpiece", which makes breathing easier and he doesn't have to worry about holding it in between plays of the game . You see my son's football organization requires them to wear a mouthpiece with a strap. A lot of straps attach to the mouthpiece, but the Battle mouthpiece is actually molding onto the mouthpiece.
I would recommend this for any one, at any level.
Thank you, Battle!
