The Karbon S Series is our super-slim, protective snap case. Visibly lined with official Dupont™ Kevlar®, a woven material that is 5x stronger than steel at the same weight, the Karbon S Series provides incredible strength and resiliency in a lightweight design. We then packed all that protection in a profile that's just 0.7mm thin, meaning you won't add unnecessary bulk to your device. Plus, each Karbon S Series case is treated and polished with our specially formulated, five-layer Evutouch® Coating for exceptionally easy-to-grip, scratch-resistant protection. Finally, since we designed our Karbon S Series cases without any metal substances or components, you'll never have to worry about interference with your wireless signals.
