Isn't it this one? https://www.amazon.com/KIWI-design-Accessories-Enhanced-Support/dp/B098JTDPQC/ I see it in stock...
I use an HTC Vive Deluxe Audio Strap that is connected through a 3D printed adapter. It works fine, but I suspect some of the newer custom-made pieces (like https://smile.amazon.com/KIWI-design-Accessories-Enhanced-Support/dp/B098JTDPQC/) are better.
Should I get this bundle https://www.amazon.com/KIWI-design-Accessories-Enhanced-Support/dp/B098JTDPQC I really like the idea of having a lens protector or should I just get the standalone strap?
