Bestop vs Quadratec for noise ratings

[TheBoogieman]

Cannot find the Sierra Offroad Trilogy (material) anywhere on the web. Looked at all of the places on the Sierra Offroad website. Two of the places (on the website) don't even exist. Best I can find (from Sierra Offroad) is Sailcloth Vinyl not the Trilogy Vinyl.

Your Google Fu is weak, grasshopper.
