Backpack Gregory Trekking Float Zulu 40 Volcanic Black MD/LG - 40L, adjustable fit

The Gregory Trekking Float Zulu 40 in Volcanic Black is a 40‑liter trekking backpack designed for multi‑day hikes, backpacking and travel. This medium/large model offers an adjustable torso fit and a ventilated suspension system to improve comfort on long approaches and varied terrain. The pack layout provides organized storage for clothing, technical gear and a hydration reservoir while maintaining balanced load distribution for more efficient carrying.

Advantages

The adjustable fit allows the torso length to be tailored to the wearer, improving posture and comfort on extended hikes. A ventilated backpanel and suspension reduce heat buildup and increase airflow, which helps limit perspiration during strenuous activity. Multiple access points and pockets enable systematic packing and quick access to essentials, and compression straps stabilize the load to reduce shifting during movement.

Suitable for

• Multi‑day trekking and backpacking trips
• Weekend hiking excursions where organized storage is needed
• Light travel and transit when a 40 L pack is appropriate
• Routes requiring a breathable suspension and adjustable fit

How to use

Adjust the torso length to match your measured torso height before loading the pack. Load heavy items close to the back and centered at mid‑pack height, with lighter items in the top and outer pockets for easy access. Use the compression straps to stabilize the load and reduce movement while walking. Route the hydration hose through the designated channels and secure shoulder straps, sternum strap and hipbelt to distribute weight effectively across hips and shoulders.

Usage recommendations

For optimal comfort on multi‑day trips, fine‑tune the torso adjustment and hipbelt fit with a loaded pack, and use the ventilated suspension to manage heat during sustained activity. Regularly reorganize frequently used items into accessible pockets to avoid unpacking the main compartment on the trail.
