Despite what it the specs say I managed to pill the lower front of the fleece. Kinda expensive for a fleece that pills after a few months. I don't even run much, just a morning jog five days a week.
It's terrific as a covering over a T-shirt base layer. It's almost like another shirt. The thing I love the most is the soft felt lining on the chin guard. Props to that. Welded lining is also a plus.
It's fit for a "slim" person, meaning that it's almost like a wet suit if you're wearing anything long-sleeve under it. I'm a skinny runner (5'9" 145lb) so if a large is tight on me I can't imagine others wearing the same size. Although, I would believe anyone getting this high-priced of a "performance" wear is not a couch potato.
The only thing I wish for is more pockets. Oh well, that wasnt what I bought it for, its supposed to be a base layer under my softshell.
Despite my huge concern about the pilling, this is definitely a great fleece.
