Story 25L of technical precision and efficiency The Citadel EDC is built tough from a dirt- and dust-resistant 420 Velocity CORDURA® RN66 fabric, and weather- and theft-proofed with YKK® AquaGuard® zippers and locking Hypalon® zipper pulls. A contoured back panel channels air to keep you cool and dry, and it also has a sternum strap to distribute the weight. Even more, it has magnetic Fidlock® closures as well as a magnetic key ring for quick-access to your essentials. As with all Black Ember bags, it's been bond-stitched for durability, and custom hardware is both aircraft-grade and laser-etched.

For California-based designer Black Ember, this isn't a misuse of the term. Specializing in technical backpacks and bags for the urban environment, their packs are beyond-durable and intuitively organized for tackle-it-all days where precision and no-wasted-energy matters. To support this level of day-to-day performance, they go all-out in-terms of materials, hardware, and build-quality. All fabrics are laser-cut and bond-stitched. Custom hardware is aircraft-grade and laser-etched. Where artfulness, precision, and efficiency overlap, Black Ember bags optimize.
