From a company that has helped pioneer the ultralight movement, the Granite Gear Blaze AC 60 Backpack is the newest installment in ultralight backpack options from Granite Gear. A simple design, crafted to shave precious ounces without sacrificing comfort or versatility, the Blaze AC 60 was designed for thru-hikers who like to go fast and light. Thanks to Granite Gear's Aircurrent Suspension system, the Blaze is able to maintain a light carry weight, just under three pounds, while still providing a comfortable ride even over uneven terrain. A 3-dimensional molded alloy frame, and padded shoulder straps and hip belt provide a sturdy carry while molded air channels, stretch mesh, and molded foam padding help to vent heat and foster evaporation even on really hot days. The pack itself is simple in design, a lidless top loader and a tall spindrift opening can be cinched down and rolled tight for a weather resistant seal. The sleeve can also be expanded when extra space is needed. The Line-loc compression system allows your load to be compressed against your back for increased agility when you're on the move as well as making it easy to lash extra gear to the outside of your pack. Amazingly lightweight and durable, the Granite Gear Blaze AC 60 Backpack has everything you need and nothing you don't for comfort during those long thru-hikes.
