I bought these because we live in earthquake territory, and I wanted them for my emergency kit so we could spot one another in a big crowd.  These shirts are fine, but just an FYI, the color is kind of pale - wierd enough to stand out in a crowd, but not really saturated with deep neon color.  It kind of reminds me of orange sherbet.  I like them, and they're fine for the purpose, but if you're looking for an aggressive color, this isn't it.  It's a gentler, nicer color.  Oh - and I got 4 shirts sent to me in 3 different shipments (wierd) and they're all exactly the same shade of orange, so I don't think I just got a one-off that isn't deep neon orange.  Glad I got them.
