I have a question for the Stowa experts. I just picked up my first Stowa from a fellow member. It came with the Black Rubber Strap that is smooth on one side and has raised diamonds on the inside. It looks like others I have seen except it does not have the Stowa Signature on the Clasp. My question is, are there Stowa Straps that are stamped and unstamped. Or is this a generic strap. Here are a few pics. Thanks for your input.
