I love this style and the weight of this fleece. I ordered more this year because I loved them so much from last year. I wear and XS. This year the XS runs a full size or more larger. Very disappointing because I do love this item and I can't order it any smaller. I'd still recommend this to anyone who can find the right fit.
With spending much time outdoors managing a horse rescue, this is the perfect pullover. It's warmth without the bulk and can be layered easily. I bought one and will now buy more - I LOVE IT!!
I have two qtr zip fitness fleece. I find they run a little large, so I need an x-small when I usually wear a small. Goes great with the quilted vest. The only downside is that after a season of washes, they get pillowed on the inside. Not as cozy as when you first wear them. But overall, a very good deal.
