If you're anything like us, you can't count the number of times your mother told you to wear a hat when it was cold outside because you lose something like 40% of your body heat through your head. And even though multiple scientific studies have repeatedly proven that idea to be untrue, unless you're ready to call your mom a liar, we think it's probably best to keep your noggin warm whenever possible. Besides, who are you gonna trust, your mom or some crazy scientist with a bunch of fancy book learnin'? Thought so. Moms know best.
