The quality of this blanket is very comfortable, durable and completely waterproof. My horses had an open wither infection and it was pretty humid here this fall so I bought her this sheet to keep her scabs from getting wet and allowing her to heal. This sheet didn't chafe her withers and I'm happy to report that I've noticed a definite improvement since she came out. I will note that this seems to work great. I ordered a 78 for my 78 inch horse and was able to upgrade to a 75 and it was fine. I decided to keep it as it has a short lifespan.
