This is a solid winter pool cover that will not allow water to pass through. Robelle 24 ft Heavy Duty Blue Winter Pool Cover for Above Ground Pools, 4 ft Overlap (28 ft Cover Size), Solid 8 x 8 Scrim, 2.36 oz/yd2, 10-Year Warranty, Style: 3524-4.
Thinest "10 year" cover i have ever purchased. Edge tore just putting clips on to hold in place. I am a 22 year above ground pool owner. If this one last one season I will be surprised. Cannot be returned once you open it and see how flimsy it is.
