A separating zipper in the same length as the front of your hoodie, or longer. My Lifehacker hoodie was 25.5 inches from neckline to bottom, so I bought a 26-inch zipper like this one for about $4.

On the fashion front, I personally fixated on Beyonce's zipper hoodie from the Lemonade special, which featured a zipper on the actual hood and which ended at the seam.

A zipper-obsessed horse in New Jersey showed off his favorite hobby when a woman approached him while wearing a hooded sweatshirt.

This is the hilarious moment a horse decided to indulge its curiosity by playing with the zipper on a woman's hoodie (pictured). The video, shot in New Jersey, has the internet in hysterics.
