Backpack Gregory Zulu 40 hiking backpack – 40 L, desert tan, size M/L

Gregory Zulu 40 is a 40‑litre hiking backpack in desert tan, sized M/L and intended for multi‑day treks and extended day hikes. The design balances load capacity and mobility, with an ergonomic suspension tailored to the M/L frame, multiple external pockets for organisation and quick access, hydration system compatibility, and attachment points for trekking poles and other gear. The pack is aimed at hikers and travellers who need a reliable, mid‑volume rucksack for backpacking and outdoor travel.

Advantages

The pack offers an ergonomic suspension system that transfers load to the hips while maintaining torso support, adjustable to the M/L size for improved fit and comfort. Multiple external pockets and stretch side pockets provide organised storage and quick access to essentials without opening the main compartment. Hydration compatibility allows integration of a water reservoir for continuous hydration on the trail, and dedicated attachment points accommodate trekking poles or ice tools. The 40‑litre capacity provides space for overnight gear while remaining compact enough for agile movement.

Suitable for

• Multi‑day hiking and backpacking trips
• Extended day hikes where extra gear and food are needed
• Outdoor travel and light expedition use
• Trail routes requiring trekking pole access and hydration systems

Key specifications

• Volume: 40 litres
• Fit: M/L frame sizing with model‑specific suspension

• External organisation: multiple pockets and stretch side pockets

How to use

Pack heavier items close to the spine and near the hipbelt to maintain balance and reduce shoulder load. Use the external pockets for items you need quick access to, such as maps, snacks or a rain jacket. Install a compatible hydration reservoir in the internal sleeve and route the hose through the designated ports to keep water accessible while hiking. Secure trekking poles to the attachment points when not in use and adjust the compression straps to stabilise the load.

Usage recommendations

Adjust shoulder straps, hipbelt and load lifters before setting off to ensure the M/L suspension fits your torso length and transfers weight to the hips. Regularly check strap tension and redistribute weight during long hikes to maintain comfort and prevent fatigue.
