This is Kenu's very first product ever! An idea born back in 2011 from the love of snowboarding and the fear of losing his iPhone 4, Kenu's founder Ken decided to invent a product that would solve just that. Featuring a 30-pin attachment that works with all early iPhones, iPods, and even iPads with a 30-pin charge port. Attaching is as easy as plugging in a cable (does not provide charging) and works with nearly all cases as well as a bare phone. The elastic coil stretches up to 4x and is reinforced with a space-age abrasion resistant Aramid fiber cord.
