Hi Dave,
Thanks for your review, and for your continued interest with Duck Covers. We are sorry to learn of your experience. The material of the Elite fabric is designed to be lightweight and breathable, however, our covers will not prevent condensation, as it is a natural occurrence where humidity is present.
This cover is designed to be water resistant. Since you have experienced an issue with the water resistance performance, and if you are still under the two year warranty period, we encourage you to file a warranty claim so we can replace your cover.
Please visit us at https://classicaccessories.com/warranty to file a warranty claim.
