This reminds me of the adverts I get when playing games on my phone about a hoodie from the brand 'Comfrt'. They have this hoodie called the 'Airplane Mode' hoodie, which they created with travelers in mind. Along with multiple pockets for your passport, snacks, money, etc., it has a built-in eye mask that can slip in and out of the hood, which I think is really neat.

You wouldn't have to risk suffocating yourself like Sarah did in this comic!
