This headband is wide and thin, so not super warm. I like that I can easily slip it down over my neck or wrap it around my ponytail when I get overheated. It also protects my forehead from my headlamp. But it is NOT reflective at all. It's a nice bright blue, but the lightning print is not reflective. I have tested this out and asked others and it is not. Since I bought it with the primary purpose of adding reflectivity to my night time running outfits, it does not fulfill that need.
