Best Covercraft Cover outdoor material?

[Bob Z.]

Hello all. I plan to buy a Covercraft interior cover (part# IC3067XX; XX = 2 digit code for material type) and use it outside; the cover is for just the top & windows with the top down (or up). Does anyone have an opinion as to which which material I should get it in? I think the best outdoor material options are "Noah", "Sunbrella", "Tan Flannel", "UltraTech", "Evolution", and WeatherShield" Except for the Sunbrella, which is much more, the others are fairly close price-wise.

Thanks in advance...Bob Z.
