Hello,
We are very sorry to see that you are not satisfied with your cover. Fabric life is affected by application, location and the physical elements the shelter is exposed to. Our standard covers have a one year warranty and if you are within that time period and something goes wrong we suggest filing a warranty claim and having it reviewed by a representative in the corresponding department. If you have any other questions or concerns please feel free to call us at 1-800-932-9344.

“I bought my 10x20 shelter years ago in 2004. I have went through 1 top and 1 set of elastic fasteners. Not bad for longevity! To prevent uv damage, I put camo tarp over it. I anchored it with ropes on a 2x6 base plate and put sand buckets on the base. It's held up to rain, wind, and Chicago snow. Excellent product. Does the job with a little care.”
