I love these sunglasses. I never remember to bring my other sunglasses but these are so light and compact the I can stash them in my sling, and always have them with me.
Even if I want to leave my sling at home, these are so compact, I can just stash them in my pocket.
They're also so lightweight that I forget I'm wearing them. I'm super tempted to see if I can get prescription lens put in a second pair that I can wear all day.
