I'm not a very outdoorsy person, so sunglasses tend to be an afterthought. I keep a pair of these in my laptop bag for work, so that whenever I need them they're there, and when I don't need them, they're not taking up valuable space. They're also great on vacation to slip into a pants pocket when you're trying to not carry a bunch of bags everywhere with you that scream, "I'm a tourist! Steal my stuff!"
