3. Setup and Adjustment
Proper adjustment of the Kriega R25 V2 Backpack is crucial for comfort and stability, especially during motorcycle riding. The unique Quadloc harness system is designed to distribute weight effectively.
3.1 Initial Fit Adjustment
- Don the Backpack: Place the backpack on your back as you would a standard backpack.
- Adjust Shoulder Straps: Ensure the shoulder straps are snug but not overly tight. The Quadloc harness will bear most of the load, so the shoulder straps primarily position the pack.
- Engage Quadloc Harness: Fasten the chest strap of the Quadloc harness. This strap is designed to sit across your chest, transferring weight away from your shoulders.
- Adjust Waist Straps: Use the alloy adjusters on the waist straps to tighten them around your waist. This helps stabilize the pack and further distribute weight to your hips. Ensure a comfortable, secure fit that does not restrict movement.
- Secure Loose Ends: Utilize the integrated strap tidies to secure any loose strap ends, preventing them from flapping during riding.

4. Operation
Understanding how to properly load and secure your R25 V2 Backpack ensures your gear remains safe and dry.
4.1 Main Compartment (Waterproof Drypack)
- Access: Unclip the top buckles and unroll the top opening of the backpack.
- Loading: Place items inside the main compartment. The white internal liner is removable for cleaning and helps with visibility of contents.
- Sealing: To ensure waterproofing, roll the top opening down at least three times. Secure the side buckles to the corresponding clips on the backpack body.
- Compression: Use the four external compression straps to cinch down the load. This prevents contents from shifting and keeps the pack stable.
