With a silicone band and watch-style metal buckle, this ID is a great-looking way to stay safe running, biking or rock climbing. In fact, I don't do anything without mine on; thanks to its handsome looks, I can even wear it dressed up.

The metal plate is designed to contain information that would be vital in the case of an emergency. If I'm ever hit by a car on my bike, I'll know the emergency responders could get in touch with my wife and/or brother, know my age and that I have a serious allergy to penicillin.

It's $30, and one size fits all.
