Familiarity: I've used it several times
Picked this up for cold weather 'only layer' Ultimate Frisbee games. Had a chance to use it during a recent backpacking trip where it dropped from 80+ to 45 degrees in a few hours. With only one more layer and a thin shell, I stayed toasty. It's so comfortable that it's one of the first things that gets pulled from the drawer. Stink factor - wash before you wear - and it'll serve you well.
