I have the fitness fleece in several colors and noticed that the darker colors (shale gray, sweet pea) seem to pill around the sleeves and hem. Otherwise they are very nice & lightweight but warm at the same time.
i have a few of these in various colors. they fit great, feel great and wash really well. No shrinking yet, but i don't put mine in the dryer though. I like the fitted seams, and the soft but not too thick fabric, its not too bulky or boxy, and flatters for a sweatshirt.
