The must-have pack for tree stand hunting has been upgraded with a plastic frame sheet and aluminum stay for ultimate comfort under load. The Fanatic Pack employs the same “Science of Sound” technology that goes into the Fanatic system and features ultra-quiet YKK VISLON® zippers, high-loft jacquard Berber fleece, and our Silent Secure closures on the top lid, eliminating noisy, loose buckles. Side pockets and winged compression straps round out this ultimate utility storage system.
