I bought the next size up after reading other reviews. It fits great. The Velcro isn’t tight enough to keep it closed. We used rope to tie it up. We shall see how it holds up this winter.This one is much thicker, comes with a storage bag, the velcro strips are much longer and comes with straps.Very happy with the purchase. I ordered the black ones.This cover is great but I wish there was more Velcro attachments. Because of this, it hangs loosely and is not too great looking. I am thinking about adding more to have a more snug fit.Material was different than I expected, It was very easy to install over the solar reel & cover.If you have a 20' pool blanket, buy a 22' cover. If 18' buy 20. It's heavy enough and sturdy enough for outdoor storage of the pool blanket in heavy winter. The package was so small I thought it would be flimsy, but it isn't. Draw strings on end allow full coverage of both ends. Will work well for summer too. Heavier would be nice, but it will likely hold up.Winter cover for my solar blanket. Needed more Velcro and I thought it would have been thicker. Looks nice! But they should have added more Velcro especially for the 20’. Not bad for the price. I will just add more tie down straps. Going to have to cover with a tarp for winterThe fabric seems to be both UV resistant and durable. However, it only comes with three Velcro fasteners. These are insufficient. I ended up adding seven stainless steel snaps along the length. This customization makes it perfect!During very hot days we like to keep the solar cover off the pool, as the heating isn't necessary. This does a great job covering my 20x40ft solar cover while it's on the reel, keeping it out of direct sunlight. Keep in mind this product is exactly 20 ft. wide, so it's important to roll your solar cover up straight if it is the same length. Any side rollup will cause your solar cover to stick out the sides.Well I thought I would get a decent fitting cover for the price that I paid over $60.00 dollars cdn. First off I have a 20 x 40 ft swimming pool, with solar blanket rolled perfect on the tube the cover comes up 4 in short and this is a thin solar cover 14 mil not a heavy like I usually buy. The cover comes with velcro along the blanket but out of 6 stips (male female) one male female doesn't line up, strips are about 8 to 10 in but only a 1 in line up. Don't waste your money.The cover itself appears to be good quality and It's large enough to fit my 18 X 34 Solar Cover.The issue I had was that the Velcro did not run the full length of the cover. There are just 4 or 5 two foot sections of Velcro which leaves gaps where critters could get up inside and damage the Solar Blanket ! Also one of the two foot Velcro sections had one side missing.I ended up ordering a 26' X 1" box of self adhesive Velcro which solved my issue.Original cover I used was a a sheet of cheap plastic I purchased for 19.00 (crap). This one looks great, is an enclosed blanket that protects my cover, easy to put on and take off. Highly recommend it.It could be a lot better if it had enough Velcro to seal it across. Instead they only have two sections with Velcro which left it with big open gaps. I used twine and bungee cord to seal the rest, but it definitely could have been designed better.Had to order the 18’ to cover the 16’ solar blanket. No zipper, just a thin rope to wind around! Stay away!
