- Fill Reservoir: Unscrew the cap, fill with water, and securely re-fasten the cap. Ensure the slide-seal closure is fully engaged if applicable.

3.2 Adjusting Fit
Proper fit is crucial for comfort and stability, especially during mountain biking.
- Loosen Straps: Before putting on the pack, loosen all straps: shoulder straps, sternum strap, and hipbelt.
- Put on Pack: Place the backpack on your back.
- Adjust Hipbelt: Fasten and tighten the hipbelt so it sits comfortably around your hips, distributing weight effectively.
- Tighten Shoulder Straps: Pull the shoulder straps downwards to snug the pack against your back. Avoid overtightening, which can cause discomfort.
- Adjust Sternum Strap: Fasten the sternum strap across your chest. Adjust its height and tension to prevent shoulder straps from slipping and to enhance stability. The magnetic bite valve attachment should be easily accessible.

4.2 Helmet Carry

5. Maintenance
5.1 Hydration Reservoir Care
- Cleaning: After each use, empty the reservoir and rinse thoroughly with warm water. For deeper cleaning, use a mild soap or specialized reservoir cleaning tablets.
- Drying: Ensure the reservoir is completely dry before storage to prevent mold and mildew. Use a reservoir drying rack or hang upside down with the opening propped open.
- Storage: Store the clean, dry reservoir in a cool, dry place, away from direct sunlight.
5.2 Backpack Care
- Cleaning: Spot clean the backpack with a damp cloth and mild soap. Do not machine wash or tumble dry, as this can damage the fabric and coatings.
- Drying: Air dry the backpack completely in a shaded, well-ventilated area.
- Storage: Store the pack in a cool, dry place, away from direct sunlight and extreme temperatures.
6. Troubleshooting
- Leaking Reservoir: Ensure the reservoir cap is tightly secured and the slide-seal closure (if applicable) is fully engaged. Check the hose connections for tightness. Inspect the reservoir for punctures or damage.
- Difficulty Drinking from Bite Valve: Ensure the bite valve is in the open position (twist to open/close). Bite down firmly on the valve while sucking. Check for kinks in the hydration hose.
- Uncomfortable Fit: Re-adjust all straps (hipbelt, shoulder straps, sternum strap) according to the "Adjusting Fit" section. Ensure the pack is not overloaded beyond its intended capacity.
- Zippers Sticking: Apply a small amount of zipper lubricant or graphite to the zipper teeth. Avoid forcing stuck zippers.
