Thanks! It’s B&S’s Ripstop strap. I bought it 3 years ago and like how it has aged. I have a blue version of it as well and look forward to whenever it gets to this stage too. The green strap lives on my CASD but while it’s out for servicing, the strap has been making rounds to my other watches.
And just for kicks, here was the strap new
it has since lightened up in color as you can see.
