I also have an all-weather one. It's from cover craft. It fits OK, not as well as the Nissan one for some reason.
I've found that you cannot use it on a car that is not clean. Or the wind will move it slightly and it will scratch the clear coat. Especially on the outside corners. I've had to buff them out 2x now. Before I realized what was doing it. Now, I wash the car almost everytime before I cover it, or I wipe it down with a cali duster first so there's no fine dust to scratch...
YMMV...

Here's the one I use:
