I used this product to cover 2 bicycle on the back of a 5th wheel trailer traveling from from Utah to Ohio and then the return trip back to Utah. It worked great, never ripped or leaked. The straps helped remove the bulk of the cover to fit around the odd shapes of the bikes. I admit, I was a little worried for the first few hundred miles wondering what I might find at the back of the trailer. Repeated inspection found no problems and we completed our trip with complete confidence in the product.
