My husband and I both own multiple quarter zip fleece from LL Bean. The only reason this does not get a 5/5 is that I feel they are a tad bit short throughout the torso. If you have a long torso, the regular may not be long enough. They hold up great after multiple washes and give you some shape, even when wearing a nice comfy fleece.
I'm 5'6" and ordered a large. It's baggy but just barely touches the top of my jeans.
I had one of these I purchased a couple years ago (Med.), and loved it. The old one kept it's shape, but did shrink (a little) in length. After reading all the resent reviews I ordered a size up which is way to big in width, and it did not shrink after washing and drying it. I will keep it because I can use it for tennis anyway, and ordered my normal size (which I recommend). The new fitness fleece is a bit more plush/softer then my old on, so I really liked that along with the great quality of it. I highly recommend this, but in your normal size.
I have many LLBean items and have never been disapointed until now. I was cooking dinner when the fish splattered on me - I had little holes all over my brand new shirt - it had melted. I have given this same style to my little grandchildren, I shudder to think what could have happened to them.
I own three of these & one hooded fitness fleece. They're great for working out, wearing outdoors, layering & lounging. They wash/dry nicely. I wear xs/sm depending if its a hooded or pullover. These are the best!
