Setup
1. Unpacking and Initial Inspection
Carefully remove the hydration pack and its components from the packaging. Verify that all included items are present: the Octane XCT pack and the Crux 70oz (2L) reservoir. Inspect for any signs of damage.
2. Preparing the Crux Reservoir
- Fill the Reservoir: Unscrew the large cap of the Crux reservoir. Fill with water or your preferred hydration liquid. Ensure the cap is securely tightened to prevent leaks.
- Insert into Pack: Slide the filled reservoir into the dedicated hydration sleeve located in the main compartment of the pack. Ensure the reservoir is seated flat against the back panel.
- Route the Tube: Thread the hydration tube through the designated port on the top of the pack and down one of the shoulder straps. Secure the bite valve to the magnetic tube trap or clip on the shoulder strap for easy access.

3. Adjusting for Fit
The Octane XCT features adjustable straps for a customized and stable fit:
- Shoulder Straps: Adjust the shoulder straps to ensure the pack sits comfortably on your back, distributing weight evenly.
- Waist Belt: Fasten the waist belt around your hips. Tighten it to provide stability and prevent bouncing during movement. The waist belt includes zippered pockets for quick access to essentials.
- Sternum Strap: Connect the sternum strap across your chest. This strap is adjustable vertically and horizontally to optimize comfort and stability.
Operating the Hydration Pack
1. Drinking from the Crux Reservoir
To drink, simply bite down on the silicone bite valve and suck. The Crux reservoir is designed to deliver 20% more water per sip. After drinking, release the bite valve to seal it and prevent drips. Use the on/off lever on the bite valve to completely shut off water flow when not in use, preventing leaks during transport.
2. Utilizing Storage Pockets
The Octane XCT offers various storage options:
- Main Compartment: In addition to the reservoir, the main compartment can hold lightweight layers or larger items.
- Waist Belt Pockets: These zippered pockets are ideal for items you need to access quickly without removing the pack, such as energy gels, keys, or a small phone.
- Front-Facing Harness Pockets: Located on the shoulder straps, these pockets provide convenient storage for smaller items like gels, maps, or a whistle.

Maintenance
1. Cleaning the Crux Reservoir
Regular cleaning of your reservoir is crucial to prevent mold and bacteria buildup:
- Empty and Rinse: After each use, empty any remaining liquid and rinse the reservoir thoroughly with warm water.
- Soap and Water: For a deeper clean, use warm water and mild soap. For best results, use a CamelBak cleaning kit with brushes to scrub the inside of the reservoir and the hydration tube.
- Disinfect (Optional): For thorough disinfection, use a mixture of 1/4 bleach and 3/4 water, or a specialized cleaning tablet. Let it sit for 30-60 minutes, then rinse thoroughly.
- Dry: Hang the reservoir upside down with the opening propped open to allow air circulation. Ensure it is completely dry before storing to prevent mold.
2. Cleaning the Pack
The Octane XCT pack can be cleaned by hand:
- Spot Clean: Use a damp cloth with mild soap and water to spot clean any dirty areas.
- Hand Wash: For a more thorough clean, hand wash the pack in cool water with mild soap. Do not machine wash, as this can damage the fabric and components.
- Air Dry: Hang the pack to air dry completely. Avoid direct sunlight or high heat, which can degrade materials.
Troubleshooting
- Leaking Reservoir: Ensure the reservoir cap is tightly screwed on. Check the bite valve for proper seating and ensure the on/off lever is in the 'on' position when drinking and 'off' when not. Inspect the tube connections for any looseness.
- Reduced Water Flow: Check the hydration tube for kinks or blockages. Ensure the bite valve is not clogged and the on/off lever is fully open. The reservoir should not be overfilled to the point of creating excessive pressure.
- Uncomfortable Fit/Bouncing: Adjust all straps (shoulder, sternum, and waist belt) to achieve a snug but comfortable fit. The waist belt is key for stability and weight distribution.
