This is an original bass strap from ZON, a high-end bass brand from the United States. The center of the strap is made of sturdy leather, and the part that rests on the shoulder uses a resilient material similar to Neotech. I think it's probably similar to a comfort strap. Recommended for those who use heavy basses. The length is approximately adjustable from 110cm to 140cm (measured with a tape measure, so there may be a few centimeters of variation). I looked it up, and it seems that it is no longer available for sale both domestically and internationally. Type: Electric Bass Shape: Jazz Shape: Multi-string Shape: Jazz Shape: Precision
