Well engineered - Deuter Futura Vario 50 + 10 Backpacks

This is my favorite for summer backpacking. The Aircomfort System keeps me so cool on hot days because of its messed back support and air ventilation on the sides and top. I'm generally rough on backpacks and I'm super impressed with how durable the mess is! Also, the front access zipper is my best friend. It lets me get right to the bottom of my pack without having to dig from the top, which is a life saver if you're as unorganized as I am!
