Voted Superb Fit- Backpacker Magazine's Gear of the Year Awards 2009When weight and durability are at a premium, the Gregory Z 65 Backpacking Backpack is the Great blend; a versatile option for weekend trips or ultra-light, multi-day backpacking trips. Its lightweight design carries up to 45 pounds by providing the Great load carrying fit via its Z65 harness and JetStream LTS (Load Transfer Suspension) suspension systems. A single lightweight, hollow stay and a molded, perforated V-beam framesheet combine for stability and to distribute weight evenly. The freely ventilated moisture wicking harnesses, waistbelt and backpanel enhance fit, aid in load transfer, provide cushioning and keep you cool on the Path. An adjustable sternum strap and load-lifter straps enhance the fit to ensure stability while on-the-go. Access to the single main compartment is gained through an extendible drawstring top entry or zippered front entry, while a large zippered front pocket and mesh side pockets provide further storage and secure places to quick stash gear. Additional performance features include an extendible lid, bottom compression straps, quick-access waistbelt pockets, weather-resistant zippers, and trekking pole/tool attachment loops. An integrated sleeve and dual exit ports make it hydration compatible.
