Bought this after reading several write ups. I am totally bull necked over 20 inches, which has also been fused. After playing for 30 minutes, it became painful to play my tenor sax. Although my previous strap was well padded and slightly elasticated to add some extra comfort, playing was uncomfortable. I used this straight out of the packet and noticed the difference immediately. Although I choose the XL, I would have liked an XXl, but they do not make one. Saying that, the XL allowed my to play for over an hour without pain. Why others have not tried to copy the Cebulla shape and style, I will never know, a true winner.
