Admit it. You've read your girlfriend's or your sister's magazines in a moment of curiosity. So the rumors are true - size really does matter! Well, at least it does when you're a fat dude delivering presents. Quite how he makes it down the chimney defies physics, but who are we to question the big man? Our Men's Size Matters ugly Christmas sweater shows Old Saint Nick doing what he does best getting stuck down chimneys hunting snacks. It's super snuggly and has extra breathing room if you're feeling somewhat "festively plump" this year. Enjoy yourself - it's Christmas. Pass the yams!
