          I live in Mass. and have a lot of snow and ice and freezing winters. This fall we have had more rain than ever before. This cover is dry and stays clean. I put our pool in 40 years ago and your cover is the best I have ever had. When I open the pool it's clean...very clean. Thank you for a great product. -Del
