Big enough for an overnight, light enough for a day hike, the Gregory Updated Zulu 45 uses a dynamic FreeFloat suspension, providing comfort in all environments. With an athletic look, full adjustability, and refined materials, we straddled the line between a daypack and overnighter. The Gregory Zulu and Gregory Jade are the perfect Family of Ventilated Hiking Packs for the day or a few days down the trail.

Open-Air, Precise Fit Backpanel: Tensioned mesh creates an open space between your back and the pack to maximize ventilation, and the adjustable torso length provides a custom fit, providing maximum comfort.
Body-Hugging, Flexible Hipbelt: The FreeFloat flexible, cushioned hipbelt conforms to your lower back and hips supporting the weight in your pack while moving freely with your natural hiking motion, and the extra large hipbelt pockets easily keep your phone secure.
Full Access U-Zip: The unique front opening on the Zulu and Jade provide access to the complete contents of your pack without having to remove the top pocket.
