There's a reason why we all throw on a hoodie whenever we want to relax and lounge around—because hoodies are one of the most comfortable things to wear on planet Earth. And when you're on long flights, if you want to catch some shut eye, it's important that you're able to get comfortable. Enter the HoodiePillow ($20, Amazon), an inflatable, over-the-neck pillow. The pillow has a built-in adjustable hood that makes you feel like you're wearing your favorite hoodie. Bonus: the hood can pull over your eyes, so you don't need an eye mask either.
