Great fleece so far, mostly positive things to say about it. I am 6'6" (thin) and picked up an XXL after wearing a similar Norrona product and finding an XL to be too small. Never wore an XXL in my life, but it does have a slim fit and I wanted room for a thicker sweater underneath. The neck is longer on this, with a little baggy-ness to it as well, but I do like this feature. However, the baggy-ness with me does tend to push the zipper portion in towards the neck, which I think I'm still trying to work out. If unzipped, the neck can also be pretty floppy, but it doesn't bother me at all. Overall, very warm for how light it is. I can see this jacket personally being worn down to 20 degrees or so with a light baselayer underneath assuming it isn't very windy, but these estimates are always a little different for everyone.
