Why are we offering a Kevlar case on Carbon Fiber Gear? Kevlar is in the same composite material family as carbon fiber, but the one problem that carbon fiber has when it comes to a phone case is its electrical conductivity feature. This can be a problem for a phone case because it can interfere with your signal reception...that's why carbon fiber phone cases generally have special cutouts or use other materials to help mitigate interference. Kevlar, on the other hand, is non-conductive and therefore cannot interfere with the signal, but since the Kevlar is dyed black, it looks identical to a carbon fiber case. Not to mention Kevlar in itself is a really cool material...bullet proof vests anyone? It's also 5x stronger than steel at the same weight.
The Karbon line comes in two formats, the S and the SI. This page is for the S, but if you're interested in the SI, go here. Here's the difference:
Made from 100% Dupont Kevlar, meant to be really slim and minimal. It's just 0.7mm thin and weighs only 10 grams. The design provides "above phone" protection on the corners, meaning if you were to put your phone face down on a flat table, it would be sitting on the corners of the case, not the glass of the iPhone.
The SI case is all about the protection. The case is military drop test approved (ML-STD-810g certified). The case fuses together both Kevlar and a shock-resistant TPU shell for the ultimate in looks and protection. It's a little bulkier and heavier than the Karbon S, at 1.5mm thick and weighing 25 grams (still very slim and light).
What Both Cases Have
Both cases are treated and polished with a specially formulated, five layer Evutouch coating which has superior scratch-resistance to help your case stay looking great over time. Its matte surface also provides a tactile feel that will help to prevent your phone from slipping out of your hands. Both cases have no metal or carbon fiber components and will not interfere with your signal.
