I've used the ARAI SIGNET XXXL for 8 years. As you may know they have stopped making it -- Arai "says" the PROFILE in 3XL is the same/better fit. I could NOT get the PROFILE over my melon. Thank goodness I found the SHOEI RF1000 full face in 3XL -- WOW !! I wish I had used it all along -- even more confortable than ARAI (IMHO) and the shield is a snap to switch out. Loving the SHOEI RF1000 XXXL.
