This is the umbrella with a completely reflective exterior for safe, dry walks on dark, rainy nights. Unlike lesser safety umbrellas that have a handful of lights on the tips or narrow reflective bands, this street-smart model becomes a fully glowing dome when light strikes it, making one’s presence unmistakably obvious to vehicles. Its waterproof polyester canopy is a subtle gray in daylight, but its high-viscosity coating is embedded with microscopic beads that reflect light, causing it to glow white in the dark. Made from lightweight ABS plastic and fiberglass, the collapsible umbrella has a telescoping handle and a wrist strap. Manual open and close. Closed: 9 1/2" L x 2" diameter. (1 lb.)
