The CITADEL 18 is a smaller version of our original urban everyday pack. The third collection in the CITADEL series brings new features while still delivering a lighter weight pack built with CORDURA's latest re/cor™ RN66, 100% recycled fabric : 420 Velocity. The new CITADEL 18 features a magnetic, separated and suspended laptop sleeve, a protective quick-access pocket and our latest T6 aluminum hardware. For the CITADEL we specified CORDURA's new 420D Velocity, the latest textile in the CORDURA® re/cor™ RN66 collection of 100% recycled textiles. Velocity has a matte-shine finish with a water resistant top coating that repels dust and dirt and a multi-layer polyurethane back side to keep water out. Black Ember is proud to be the world's first brand to collaborate with CORDURA® Advanced Fabrics on the launch of its new CORDURA® re/cor™ RN66 collection. It is the first 100% recycled nylon 6,6 textile from CORDURA®. When compared to virgin N6,6 production CORDURA® re/cor™ RN66 produces 83% fewer GHG emissions, consumes 82% less energy and uses 57% less water. The CORDURA® re/cor™ RN66 refers to recycled Nylon 6,6. That 6,6 rating means it's a high tenacity nylon and that it is ultra-durable. CORDURA® re/cor™ RN66 has passed the brutal barrage of tests that make a woven nylon CORDURA® brand certified. Dimensions 17" x 11.5" x 6.5"
