Granite Gear has been building packs specific to the needs of long distance hikers since 2003 when we introduced the award winning Vapor Trail and Nimbus Ozone, winning Backpacker’s coveted Editor’s Choice award, as well as the respect of the long distance hiking community. Our objective has stayed the same! Develop and build packs that are as light as possible while still offering optimal comfort, suspension, compression and exceptional durability.Like its predecessors, The Blaze AC 60 is Spartan in its simplicity and features our engineered Air Current suspension. The Air Current suspension consists of a 3-dimensionally molded alloyed frame, our quickest torso length adjustment system, padded shoulder straps, and a swappable hip belt for a custom fit. The AC frame has molded air channels, works in conjunction with a molded foam pad and durable stretch mesh to aid in venting heat and moisture away from the back; allowing for natural evaporative cooling. The pack body is a simple, lidless top loader with a tall spindrift opening that can be cinched and rolled down tight for weather resistance and also expanded when extra space is needed. The arched Line-Loc compression system allows the load to be cinched tight in every direction (side, front, and top) as well as allowing additional gear to be lashed to the pack. The Line-Loc cord can easily be replaced if it wears out from extended use. Durable and versatile stretch mesh pockets on the bottom of the pack sides work well for water bottles, while the tall front center pocket is great for damp tarps or ultralight tents.
