From the pattern description:
I get COLD, really cold, all winter long, so cold! I decided I needed a glove for my chest, something thick and warm; a vest that would hug my torso and keep my core body temperature on the ups.
So, I envisioned this, and made it in a weekend! You gotta love super chunky yarn for the speed in which you can whip out something to keep you from freezing.
To get the hug (abrazo in spanish), this pattern is designed to fit with 2” of negative ease. There are simple cables going up the front princess seams of the vest, terminating before the shoulder seams to eliminate any unflattering bulk -- a little design element that breaks up any knitting monotony and creates even more cling!
