As you can see in the video below, even the slightest flash of light is enough to illuminate the entire bag like the harvest moon. It’s like having a giant cat cornea slung over your shoulder. Even better, the waterproof lining will keep your 13-inch laptop dry, and your rear-end shining well into the winter season — well after those wussy fireflies have called it quits. Ostensibly, all this glowing material is meant to keep you safe when biking in the dark, but you may also have to worry about an even greater threat: giant-mason-jar-totin’ toddlers. [Rickshaw]
Doesn't look half bad :o Seems to me it would get dirty pretty fast though.
Luminescent would indicate that it produces its own light. This bag is reflective which means it needs other lights like car lights to make it glow.
