I have had this fleece for several months and washed it several times. I have not had any issues with pilling. I am very impressed with this fleece.
I have washed mine about eight or ten times. The inside is really soft and looks like fleece. It looks just a tiny bit scruffy, but I wouldn't consider it to be pilling at all. (It may have always been a little scruffy, I just don't remember). The outside is more a tiny knit than a fleece and is less soft and more smooth. The outside hasn't pilled at all and still looks brand new. I have loved Jack Wolfskin brand since I was in Germany many years ago.. It is a very high quality brand there. The one down side I have found with this particular jacket is that dog hair tends to stick a little more than average..
