Earlier this month NikeLab unveiled their incredible ACG Spring 2015 Collection. Part of that range was the military-inspired ACG Responder Backpack, a handsomely reworked iteration of the classic SFS Responder. Made with durable, weather-resistant materials, it features a unique X-shaped, four-way Nike Quad Zip system that allows you to completely open the bag for easy interior access. Padded, adjustable shoulder straps and a cushioned back panel with strategically placed mesh offers plenty of comfort and reduces shifting, while detachable, zippered side pockets make room for small items and valuables. Measuring in at 21-inches tall, 16-inches wide and 7-inches deep, the sturdy and beautiful NikeLab ACG Responder Backpack is available now for $300.
