The Gregory Z40 is a well-established pack for overnight trips due to it having multiple compartments, so a sleeping bag can be stashed away from gear needed during a walk. It’s built around a back system that holds the body of the sack away from the torso to create a lot of airflow, but it isn’t too precurved to reduce the usefulness of the space in the main compartment. The back system also twists a little with the body to allow it to maintain a close fit when scrambling. The body contact areas have open mesh to reduce the build-up of sweat and the overall effect is a close-fitting yet comfy carry. The body has a main compartment with top entry but there’s an additional entry to the base compartment or the internal divider can be zipped out to make one big compartment. On the front is an additional bellows compartment that’s ideal for quick access to waterproofs. If all that wasn’t enough there’s also front access to the main compartment. All those zips and compartments you will love, hate or tolerate; they probably add a little to the weight of this pack as at over 1.5kg it’s one of the heaviest here. You also get good compression straps and mesh side wand pockets that are very useful, and overall the Gregory Z40 is great if you prefer more compartmental organisation to your gear, coupled with good airflow across the back and good stability.
Capacity 40 litres

The Gregory Z40 is a very comfortable pack for shorter multi-day trips if you prefer to stash gear in compartments and don’t mind the slight increase in weight.
