We kept the best parts of the original RUSH12 and upgraded other areas to create one of the most universally adaptable packs on the planet. We&';ve added a hidden CCW compartment, given the eyewear pocket more room, incorporated a padded laptop sleeve, and moved the hydration tube ports to the rear for more versatility. From outdoor activities to duty applications to office use, you won't find a pack that has a little of everything in all the right places like you will with the RUSH12 2.0.
