The high-performance Gregory Z45 employs lightweight, high-tenacity fabrics and an innovative suspension system to provide streamlined load carrying capability. This versatile is ready made for technical day hiking or fast-and-light backpacking.
Having spent numerous years and countless miles out on the trail, the designers at Gregory are well aware of the problems that arise from ill-fitting backpacks. Unwilling to compromise comfort or load-carrying capability, Gregory's commitment to providing the perfect fit is evident in the technology used in the Z45's harness and JetStream LTS (Load Transfer Suspension) suspension systems. A single lightweight, hollow stay and a molded, perforated V-beam framesheet work in tandem to support the stability of the Z45 by distributing weight evenly and transferring the load to your hips. Raised contact points at the scapula pads and lower lumbar pad create substantial space between your pack and the pack allowing "true ventilation". The ventilated moisture wicking harnesses, waistbelt and backpanel enhance fit, aid in load transfer, provide cushioning and keep you cool on the trail. An updated proprietary waistbelt system allows you to choose between three different adjustable lengths to provide optimal fit. An adjustable sternum strap and load-lifter straps further enhance the fit of the Z45 and ensure the stability of your load, allowing convenient on-the-go adjustment.
The single main compartment of the Z45 has an extendible drawstring-closed top entry and a zippered entry allows full side access to the pack body. A large stretch pocket on the face of the pack offers convenient storage for gear or wet clothes. The Z45's extendible lid includes an integrated stowaway pocket and can be removed entirely when you want to travel faster and lighter.
The Z45 also includes side compression straps, quick-access waistbelt pockets and gear loops. An integrated sleeve and exit ports make the Z45 hydration system (sold separately) compatible.
Available in your choice of color options, the Gregory Z45 comes in S (2563 cubic inch storage capacity), M (2807 cu in) and L (3051 cu in) sizes.
