Main Compartment Access and Waterproofing
The main compartment features a roll-top closure to ensure 100% waterproofing.

Maintenance
Proper care will extend the life and performance of your Kriega US-20 Drypack.
- Cleaning: Clean the exterior with a damp cloth and mild soap. Avoid harsh chemicals or abrasive cleaners. For stubborn dirt, a soft brush can be used.
- Drying: Allow the drypack to air dry completely before storage, especially the internal waterproof liner, to prevent mildew.
- Zipper Care: Periodically clean and lubricate zippers with a silicone-based spray to ensure smooth operation and prevent corrosion.
- Strap Inspection: Regularly inspect all straps, buckles, and attachment points for signs of wear or damage. Replace any worn components to maintain security.
- Storage: Store the drypack in a cool, dry place away from direct sunlight when not in use.
Troubleshooting
If you encounter issues with your US-20 Drypack, consider the following common solutions:
- Water Leakage:
- Ensure the roll-top closure is rolled down at least three times and the buckles are securely fastened.
- Check the internal white waterproof liner for any tears or punctures.
- Verify that the external zippered pockets are not mistaken for the main waterproof compartment, as they are not fully waterproof.
- Loose Mounting:
- Re-tighten all Hook-Straps and ensure Subframe Loops are securely anchored.
- Confirm that the drypack is not overloaded beyond its capacity, which can strain mounting points.
- Difficulty with Zippers:
- Clean any dirt or debris from the zipper teeth.
- Apply a zipper lubricant to improve movement.
