Gregory Z55 (2014) Internal Frame Backpack

Updated for 2014! Striking a balance between weight and durability, the high performance Gregory Z55 internal frame backpack employs lightweight, high tenacity fabrics and an innovative, streamlined suspension system to provide load carrying capability without the bulk and burden of a full blown expedition pack.Well aware of the problems that arise from ill fitting backpacks, Gregory is committed to providing fit, comfort and load carrying capability. This commitment is evident in the technology used in the Z55's harness and CrossFlo suspension system. A lightweight wire X Frame and a trampoline style backpanel work in tandem to support the stability of the Z55 by distributing weight evenly and transferring the load to the lumbar pad and waist belt. Die cut foam on the harness and waist belt adds breathability and decreases weight. The ventilated moisture wicking harnesses, waistbelt and backpanel enhance fit, aid in load transfer, provide cushioning and keep you cool on the trail. An adjustable sternum strap and load lifter straps further enhance the fit of the Z55 and ensure the stability of your load, allowing convenient on the go adjustment.The single main compartment of the Z55 has an extendible drawstring closed top entry, and a U shape zippered entry allows full front access to the pack body. A large zippered front pocket provides a secure place to secure additional gear and a huge bucket pocket with mesh sides offers convenient storage for gear or wet clothes. The Z55's floating lid includes an integrated stowaway pocket. All of the zippers used on the Z55 are designed to be weather resistant.The Z55 also includes side and bottom compression straps, quick access waistbelt pockets, two exterior stretch water bottle pockets and hideaway gear loops.
