20mm 120/80mm I like Diabolique straps. He’s the only person making waterproof leather. But he also makes these custom canvas straps with designs or drawings. This one has an American flag and the moon lander scene. It also happens to be 120/80, which is too long for me. I always have straps made at 105x75. This one was gifted to me after a purchase of other straps and a delay. It has my name on the back, which is why I’m not including a photo. The front is canvas, the back is his waterproofed leather. $55 and proceeds will be going towards www.pasadenahumane.org. EDIT: Just saw the weird speck on the flag side. That was an eraser or something. I blew it off. Strap is unused. Unmounted.
