TUBE SIZING INDEX

Measurements should be taken at the high point where the tube will ride, usually the sternum or lower rib cage. Alternatively waist measurements can generally work.

Note: All Neoprene tubes (Ocean Tour, Ocean Trek) will not work with a Seat Back that extends over the height of the cockpit rim.
