A newly acquired grail strap for me. A first generation red twin-pad X-33 strap...on a Gen 1 X-33 of course.
I've been looking for a good one for years. Problem is they weren't rugged. The padding cracked and I've read even bled their dye onto the wearer, so I pretty much had to find one that hadn't been worn for 15 or 17 years.
Mine may look good, but has become so stiff I don't dare bend it around to buckle it for fear it will crack. Just for looking and collecting...but I'm happy with that!
Here are some ads/literature with that strap from around the time the model was launched in 1998 as "The Mars Watch".
