Mind boggling volume, but slim and manageable when empty. The ideal bag for heavy-duty messenger work. In addition to the cross-chest stabilizer strap, the Kremlin messenger bag also includes a waist strap attachment point. Extra features include a secret stash pocket and front utility buckles for external rain gear storage. Designed for the long haul... ten hours a day in the rain, mud, snow, and grit. Our messenger bags are constructed with the most rugged assembly of industrial materials and hardware available: military spec. seam binding, 1000d Cordura shell, 18oz. weatherproof truck tarp liner, and nylon 69 thread.
