CamelBak Octane 16 Hiking Hydration Backpack with 70oz Fusion Reservoir

The CamelBak Octane 16 Hiking Hydration Backpack with 70oz Fusion reservoir is engineered for hikers who move fast and need hydration without excess weight. Its 3D Vent Mesh harness uses ridged foam and breathable mesh to promote airflow, keeping you cool during sustained climbs. Dual adjustable sternum straps provide a secure, customizable fit that stays stable on uneven terrain. The main compartment holds essentials, while a stretch overflow pocket expands for extra layers or shoes. Trekking pole attachment keeps poles accessible when the trail changes.

CamelBak Octane 16: Lightweight Comfort for Fast Hiking

This pack is designed for high-output day hikes and longer treks, balancing ventilation and carry efficiency. The 3D Vent Mesh harness helps manage heat, and the dual sternum straps let you fine-tune the fit. The roll-top closure and side zip offer flexible access to your gear.

Using the Roll-Top Closure and Side Zip

The roll-top closure allows you to compress the pack for a lower profile or expand it for extra gear. The side zip provides quick access to the main compartment without unrolling the top. For best results, pack heavy items low and close to your back.

Filling and Installing the 70oz Fusion Reservoir

The Fusion reservoir is easy to fill: open the wide-mouth cap, fill with water, and close tightly. It slides into the dedicated sleeve in the pack, with the hose routing through the shoulder strap. Ensure the hose is connected and the bite valve is in the open position.

Compatible with Larger Bladders?

While the pack is designed for the 2.5L reservoir, it may accommodate up to a 3L bladder depending on shape and how much gear you’re carrying. For optimal fit and hydration, we recommend using the included Fusion reservoir.
