If I had an award for the coziest sweatshirt (a hard feat, I know!), I'd give it to this one: the Tupa Hoody by Io-Bio ($130). Most sweatshirts are made out of cotton and grow rough with each washing, but the Tupa Hoody is 100% merino wool which means it's way off the "soft-for-a-sweatshirt" charts. "Butter" would be one adjective to describe it, while "clever" is another; Thumb holes make sure your hands stay nice and warm inside those ski gloves. Whether you're sleeping in this thing or wearing it outside, you won't want to take it off. The lotus drawing on the arm is a nice touch too.
