Mono Cases The Betty Strap Long

Relative comfortable strap, a bit less slick than my leather strap so it straps itself into loose shirt easily and may pull it down a bit. The main concern is that the strap is a bit flexible, and it stretches sometimes when playing inducing noises via body resonance to my bass. Therefore wouldn't use at gig, only at practice/home. It may be, that it evens out with use, but after a month I have to manually stretch it to avoid body resonance noises from unwanted stretching of the trap mid-play.
