The material for the lugia hoodie is fantastic! It's sublimated nicely, the colors are vibrant, it's cozy and warm, and the design is done diligently (ie there were no printing errors on any parts of the product). PublicSpace always knocks their hoodies out of the park!
I am 5'9" and 140, with a feminine build, and ordered the small. It fits me with sleeves long enough for my arms and a long enough torso, and isn't so tight the neck is choking me. It has a little wiggle room in the small as well, and is not tight/form fitting. If you're slender/petit, a small will have lots of wiggle room, but if you're larger, then I definitely recommend sizing up.
