From long haul day hikes to overnight backpacking trips, the Gregory Zulu 40 Backpack has you covered from A to Z. Although it's the smallest pack in the Zulu series, this 40 liter option will still comfortably support loads up to thirty five pounds with its CrossFlo DTS suspension and lightweight, flexible spring steel frame. CrossFlo DTS is specifically designed to maximize space between your back and the pack to help keep things cool and comfortable, and Gregory placed EVA foam along the hips and shoulder harness to keep your load comfortably when you're on the trail. Packing and organizing gear in the Zulu is made easy with the large U zip access panel, and the front stash pocket is an ideal spot to store any extra layers or maps you might need quick access to. Gregory also threw in an integrated rain cover, so you'll always be ready for those right on cue afternoon rain showers that like to frequent the alpine.
