A bit like leather/rubber straps made by Hirsch but more affordable! Instead of using the vulkanised rubber, this one use silicone. Still, it's comfortable to wear and fine in humid weather. The ribbing is different between the two with this one having a valley instead of a peak in the centre. Big props for using quick-release spring bars!
Very beautiful strap. I didn't have a chance to use yet, but it seems well made. Just like in the photos, nothing to complain.
