Be honest, you've been curious. Do these things work? Or maybe you know they work but are just afraid they don't look "core" enough.We used to feel the same way. But we got over it. An inflatable neck pillow is gold on a long bus trip or flight. They blow up in a few puffs and hold their shape for hours. It can be impossible to find a comfortable position to rest or sleep when you're on a bus originally used for third graders in the 70s or on that dreaded airline middle seat. An inflable neck pillow cures the problem. They are incredibly lightweight and compacat and slip easily into your daypack when uniflated. So stop worrying about looking cool. Just take what you need and enjoy your trip!
