The Gregory Zulu 40 is a men's all-around pack aimed at day hikes and short overnight trips of three to five nights, built around Gregory's CrossFlo tensioned mesh back panel for ventilation and a spring steel frame for load transfer. At 1,311 g for 40 liters it comes to about 33 g per liter — on the heavier side for its volume class, reflecting the fully adjustable back length, PFC-free DWR-coated 210D Honeycomb Cryptorip nylon shell, and the FreeFloat hip belt with pockets rather than a stripped-down ultralight build.
The pack claims a 16 kg maximum load, plausible for its frame and mesh back. Organization runs through a top lid with its own pocket and a front-panel J-zip, plus two stretch-mesh side pockets and a front stretch pocket, side-only compression straps, and side loops for trekking poles. Hydration compatibility and an included rain cover round out the trip-day features.
With partially recycled fabric and a one-year warranty, it reads as a durable, adjustable workhorse rather than a grams-counting choice — suited to hikers who prioritize back ventilation and fit over shaving weight.
