Fairbanks Snow Travelers

I've taken a look at seat covers for my 1995 skidoo summit and 1996 skidoo touring E and it looks like saddleskin makes one that typically cost around $111-120. Does anyone have any experience with these? Are they made out of decent vinyl that would not crack at at -20?

Also looking at material and just making them...

and yes, I do have the sewing machine that can handle it.
