The ADCO Tyvek Designer Series Plus Wind cover is designed to accommodate 31'7" to 34' travel trailers. This cover has a white Tyvek top panel and gray polypropylene sides. Both the top and side panels have triple layer protection. This cover is particularly resistant to blowing wind and UV radiation and can be used in any climate. The slip seam strap system tightly fits the cover to the trailer, minimizing impact made by the wind. Circulation is provided by the side panel's built-in vents, which prevent moisture from collecting inside.
