The Gyrfalcon is the most advanced, feature-infused pack from Maxpedition. It has a removable, adjustable internal frame and features a removable waistpack as well. With 36 liters capacity (2250 cu. in.), the Gyrfalcon can accommodate a large amount of gear and supplies, but it also has a fully modular exterior for attaching additional gear. The wide, load-bearing waist belt efficiently transfers the load from shoulders to promote comfort over the long haul.
