"After getting in the habit of running for an hour early in the morning before my family wakes up, I didn't want the pitch blackness to stop me! I run 5:30 to 6:30 a.m. on some country roads, and now the sun doesn't rise until after, so wearing this Nathan Vibe Reflective Vest ($25) makes me feel much safer. I like that it's lightweight and thin, so I barely notice I'm wearing it. All the white parts are reflective, so it offers full visibility in the front and back, and the size is adjustable, so it fits over anything I wear, from a thin tank top to a light jacket." — Jenny Sugar, contributing editor, Fitness
