Troubleshooting
Hydration hose is difficult to route.
Ensure the hose is fully inserted into the reservoir and check for any kinks or obstructions in the routing channel behind the hip pocket.
Pack feels unstable during rides.
Ensure the hipbelt is positioned correctly on your iliac crest and tightened snugly using the ErgoPull system. Adjust shoulder and sternum straps for a balanced fit.
Zipper is difficult to open or close.
Check for debris or fabric caught in the zipper teeth. Gently work the zipper back and forth. Apply a small amount of zipper lubricant if necessary.
Water flow from the bite valve is weak.
Ensure the bite valve is in the open position (usually by biting or twisting). Check the reservoir for adequate water level and ensure the hose is not kinked. Clean the bite valve mechanism if it appears blocked.

Setup, Compatibility & Care

Insert the reservoir into the dedicated sleeve within the main compartment. Route the hose through the designated channel behind the hip pocket, ensuring it can reach comfortably. Attach the magnetic bite valve to the magnetic clip on the hipbelt.
- Tool Roll: Unroll the included tool roll and organize your essential bike tools (multi-tool, tire levers, CO2 cartridges). Securely roll and place the tool roll into its dedicated compartment.
- Adjusting Fit: Loosen the hipbelt and shoulder straps. Put the pack on and wrap the hipbelt around your waist, ensuring it sits comfortably on your iliac crest. Tighten the ErgoPull closure system for a snug fit. Adjust the shoulder straps and sternum strap for optimal comfort and load distribution.
