Is the Zulu 40 a giant daypack or a fast-and-light overnighter? Take your pick—the answer is both. Big enough for supplies for two on long, sunup-to-sundown adventures, this generously sized yet light and agile pack can even work for nights in the wild when the gear list is shorter than usual. You’ll appreciate the dynamic fit of the Free Float suspension on the trail just as much as you’ll love the U-zip panel access when you hit camp. Free FloatThe new Free Float system incorporates adjustable torso length into its tensioned, open-air backpanel. It’s a revolutionary approach to ventilated suspension, and Gregory could have stopped there—but they didn’t. Proprietary Free Float flex panels allow the the hipbelt to pivot and flex with the natural movements of your body. This provides a floating sensation on the trail, and allows the hipbelt to wrap smoothly and comfortably around you lower back and hips.
