Reader Chris mentioned this in a post reply, and I thought it important enough to call out in a review. What you see pictured is the Road ID.
It's a pretty simple concept, really: print some basic information on a wristband and wear it when you're out running, cycling, whatever.
My father bought one for me when I was riding a lot, and I've since added it to my running repertoire. There are a few reasons I prefer this over some crap scribbled on a piece of paper and shoved in my pocket:
- It doubles as a light reflector. You can see for yourself in the testimonials that this simple attribute has saved lives: when a car's lights hit the reflective material, you are more visible than you were when you weren't wearing it. You may have other reflective material on other parts of you, but if that angle doesn't hit quite right you may not be visible enough.
- It is waterproof and easy to quickly put on. That scribbled note may get wet, you may not feel like writing stuff down, you may even forget to grab your id/insurance card/whatever in your haste to get on the road (if you're like me, anyway).
- It is easily visible to paramedics or anyone else who may need to access that information. Admit it, you never think you're going to fall or have issues. You prepare pretty well, but you figure you won't fall on most (or any) of your outings. My father cycles quite a bit, and on one of his solo outings a couple of years ago he fell and blacked out—the folks who saw him fall were able to quickly call my mother and find out who he is without digging in his bag or pockets.
I really recommend you nab one of these and make it a permanent part of your fitness/activity wardrobe. It just makes sense.
