Review on FYLARFLY LED Light Up Reflective Running Vest - USB Rechargeable, Machine Washable, Adjustable Waist, Phone 🏃 Pocket - Flashing Motorcycle Vest for Men, Women, Kids - Safety Gear & Gifts for Runners, Walkers by Scott King

My wife says: "This reflective running vest is very discreet. It's quite comfortable, almost invisible when running. The light appears bright enough to be noticed, almost bright enough in low light to illuminate a small portion of the surroundings. It fit well when I was wearing it in a sweatshirt underneath, but when I was just wearing it with a long sleeve shirt it wasn't as tight and felt like it was flapping around. I can't tighten the straps. I run a women's medium size (sometimes small) and a size small for gender neutral t-shirts."
