Big enough for an overnight trip, light enough for a day hike, the Gregory® Zulu 45 Backpack provides versatility in all environments. The FreeFloat flexible, cushioned hip belt conforms to your lower back and hips supporting the weight in your pack while moving freely with your natural hiking motion. 3D design conforms to the shape of your body, seamlessly providing the padding and support needed to carry heavy loads. Extra-large hip-belt pockets keep your phone and other essentials secure. Open-air, precise-fit back panel with tensioned mesh creates an open space between your back and the pack to maximize ventilation. Adjustable torso length provides a custom fit. Full-length tensioned mesh creates space between your back and the pack to allow for heat to escape and air to flow freely to cool you down. The perimeter frame provides stable, yet flexible support. Perforated shoulder harnesses with ultradurable Lifespan foam maximize airflow, comfort, and longevity. Full-access U-Zip front opening provides access to the complete contents of your pack. The Zulu 45 backpack features a top zippered pocket with reflective attachment points, key clip, and internal zippered security pocket. Other storage highlights of this Gregory backpack include dual side stretch mesh pockets with pass-through for over or under compression; front stretch-mesh pocket with durable fabric front panel and secure buckle closure; adjustable attachment loop and upper shock lock to secure trekking poles or an ice axe; and custom ComfortGrip molded zipper pulls. Hydration sleeve with SpeedClip hydration hanger, compatible with Gregory's 3D Hydro reservoirs (reservoir not included). Construction details: alloy steel frame; 400-denier 40% recycled polyester body fabric; 420-denier nylon bottom fabric; 135-denier 40% post-consumer recycled polyester lining; and durable water-repellent (DWR) finish.
