filaments. These filaments are then combined by the thousands to make strands that are interlaced into a weave that is as strong as steel while one-tenth its weight. Aluminum however, is one-fourth the weight of steel. Resin is then impregnated into the cloth creating the strength and rigidity of carbon fiber. Once carbon fiber is fashioned into the trademark Zero Halliburton case, the end product is an absolutely stunning glassy black finish with a subtle carbon fiber weave. Best of all carbon fiber is nearly impervious to wear. Dimensions: 13 x 18 x 4.5 in. Style #: P-4 Stealth P4-Stealth 4" Carbon Fiber Attache is made from the same material as the Stealth bomber.
