Xpress Factory Boat Covers

Can anyone who has the Xpress boat cover on an X21 or X19 provide some information on the cover?
I currently have a 2005 X21LE with a 16 year old Sunbrella custom cover and I'm wondering what owners think of their Xpress cover.

I'm interested in:

1. How well does it stays secured while traveling at highway speeds?
2. How well does it repel water while the boat is sitting in the rain? (Does rain water pool up on the cover?)
3. Does water leak through the cover?
4. How well does it "holds up" as compared to a Sunbrella custom made cover?
5. Any other concerns/observations are welcome.

Thanks in advance!

I went with a Sunbrella custom cover. In my opinion the custom cover can't be beat. I didn't get the cover from Xpress but I doubt it would be anywhere near the quality of the custom.

Bought the factory cover for my 2021 X19 and it does not fit over the Ultrex/360. Very nice cover otherwise.

"It does not fit over the Ultrex/360" Thank you! Decision made; it's a custom cover for me!

Thanks again!
