Gregory Zulu

Yes, 55 liters is the sweet spot for most 3-to-5-day excursions. It provides enough volume for a tent, sleeping system, and food supply without being overly bulky, provided you pack efficiently.

The adjustable torso allows you to slide the harness up or down to match your specific back length. Getting this fit right is crucial because it ensures the weight of your pack is distributed correctly onto your hips rather than pulling on your shoulders.

The suspension system creates a physical gap between your back and the pack, which allows for significant airflow. While it won't eliminate sweat entirely during strenuous climbs, it is noticeably more breathable than a pack that sits flush against your back.

Yes, the Zulu is hydration-compatible and features an internal sleeve and routing port for a reservoir hose. It is designed to accommodate most standard-sized hydration bladders.

Because of the adjustable torso length, this pack is quite versatile and can be dialed in to fit a range of body types. However, if you have a very short or very long torso, it is always best to measure your back length and compare it to the manufacturer's sizing guide before purchasing.

The internal frame is designed to provide structural support and stability for heavier loads, not to restrict your movement. It helps transfer weight to your hips, which actually makes the pack feel more agile and balanced on uneven terrain.
