The Sousaphone Shoulder Pad is made of neoprene with an anti-microbial removable insert pad for comfort. This internal cushion can be increased or minimized as desired with other padding. The cover is weather resistant and non-marring to the instruments finish. The non-skid surface that rests against the instrument prevents slippage while marching. The Pad attaches easily to the upper tube using adjustable hook-and-loop fasteners which hold it securely in place yet can be removed quickly and easily to clean the instrument as well as the pad.
