Yup, I had the same question and emailed him the day I made this post. He assured me they did have the window cutout. And my Dino hide one has it too.

It's good you asked. When I got my first one the pattern we initially talked about didn't have the cut-out. I don't think Tim has a ProVari, it seemed to take him awhile to grasp the concept that a cut-out was essential. I'm really glad I insisted on it. I don't know how tight your sleeve is, but I still have to use something to push it out when I change the battery. It would have driven me nuts having to push it out of the sleeve every time I wanted to look at the LED.
