Saw this on facebook and took a chance, so happy I did. This thing is so beyond what I thought could be reflective it's literally insane. Even with my cars hazards and no lights on from 40ft away it was still blinding..... pictures in my room are of my old backpack vs this one, the others are me wearing no backpack 40ft away from my car, then with the backpack. Without a doubt would recommend this to anyone and everyone
