Fitness fleece is all I need to get through mild Texas winters: probably my all-time favorite LLB product. I'm just over 5'3" - 125ish lbs. and the XS fits great.
I just ordered the jasper yellow pullover and matching Thinsulate vest (so beautiful!) and hope it will eventually cool off enough to wear them.
This fleece isn't Polartec: it has a smooth knit inside surface and the outside is so soft it's hard to describe. It eventually pills a little in the wash, but the colors stay true and they stay warm. The fabric is amazingly warm for being so lightweight.
ordered in XS - I wear a size 4, 4 petite if I can find.
the XS in this is way too big. it's boxy too despite the princess seams. sad as colors and construction are both great. I have dogs I live in fleece half zips and had had ordered 2 with a view to getting more colors :(
This fleece is so lightweight and comfortable that once I tried it on to see if it fit, I just didn't take it off. I got an X-large size even though I usually wear a 12 or 14. This gives enough room to wear a layer under it.
Originally, I bought the Fitness Fleece on sale and liked it so much that I have gotten 4 more. They are great for teaching, coaching and playing tennis. I look forward to the new colors each season.
