This was a huge lifesaver after getting new puppy. Giving them a cozy place to sleep & covering the crate kept her from crying & whining. If they can’t see you, they won’t bark or whine. Helped her sleep so much better too. You NEED to buy this!it isn't as light canceling as i was hoping, you can but it still helps get my puppy less rowdy and ready for bed.I like this fabric. It has sheen to it and it won't collect fur like my other one with geometric shapes that is cotton. My puppy likes to eat anything and everything...so he pukes occasionally in his crate and these really help keep it off my walls. it is easy to clean.It works for our use. It’s light enough for air to move through, Velcro is a little flimsy.Fits small crate perfect!The covers are really nice. They pleasant to look at and also look easy to clean. They were a bit tricky to put together, not hard but make sure you aren’t in a hurry! Also, they aren’t easy to fold neatly. I don’t use them full time so I keep them in a cabinet and since they are a slick type of material (I’m hoping waterproof) it’s hard to fold and stay folded. I will definitely by again if they prove durable. I think they will.However! I did receive the wrong size twice! The first time i excepted as my fault somehow, so i ordered another because i really needed the smaller size quickly. I like the looks of the one I got so i kept it because i do have 2 larger cages i don’t use often. Well, with my second purchase i received the l wrong size larger cover again! The timing would have been perfect as I needed it that day! But no, it was wasn’t perfect, because it was the wrong size again! They sent another larger one! I might keep it to avoid the hassle of returning and i do have a cage it will fit, but I don’t use larger cages to go to the vet!I’m going to order from another company for the smaller size but I still am a fan of this company’s product and have always been happy with their products. I definitely will order from them again!I only needed something cheap but yet fairly water resistant from rain, nothing fancy, for a feral cat that an older friend is trying to accommodate out in his yard. One reviewer had taken pictures and commented on my same issue but I missed his review, I guess. I thought maybe there was some kind of elastic to run under the cage that ran from each bottom side of the cover to keep it in place. It does have the velcro pieces to close off each corner and side but one swift breeze for an outside cat and this thing is gone. It's thin and lightweight but should be fine for shade and most rainfall. The material is very similar to lightweight parachute pants for those that are my age and remember them. For a feral cat it's better than just being out in the elements at least.SOLUTION: We can either put a lightweight rock or something on the corners of the cage to hold it down or I can run out quick and buy some elastic and sew a few straps across the bottom edges and just slide the cover on from the back.So....it's decent for the price for indoor use but really needs to be altered for outdoor use.Slips right on a 30" dog crate. Velcro closures are perfect. Light polyester material.Well made and just what I was looking for.
