Classic model made of high quality synthetic material and special synthetic lining to prevent sweat absorption. It has internal foam to evenly distribute the weight of the instrument on the musician's shoulder. The tip where the instrument is engaged was developed with an internal reinforcement in order not to "sag" and with the action of time, not to escape the instrument.

It has 7.5cm in width and variable length between 1.00 and 1.45m.
