The Nite Ize SlapLit features that same Slap It to Snap It technology with an added dimension of LED illuminating functionality. Made of durable nylon patterned with a reflective spider web design, the SlapLit is powered by a bright, easy-to-activate LED that lights up the entire wrap. Turn it on, slap it on your wrist, upper arm, or ankle (or any tubular-shaped object, for that matter), and you've got instant nighttime visibility. Lightweight and durable, the SlapLit is perfect for after-dark lawn games, running, walking, cycling, outdoor evening concerts and events. Use and reuse countless times, the SlapLit can be straightened with a simple twist of the thumb and stored flat, or hung in its straightened form and used as an LED marker beacon.
