6. Maintenance

6.1 Bladder Cleaning

1. Empty Bladder: After each use, completely empty the bladder.
2. Rinse: Rinse the bladder and hose thoroughly with warm water. For a deeper clean, use a bladder cleaning kit or a mixture of warm water and baking soda/lemon juice.
3. Dry: Ensure the bladder is completely dry before storing to prevent mold and mildew. Use a bladder dryer or hang upside down in a well-ventilated area.

6.2 Vest Cleaning

• Hand Wash: Hand wash the vest with mild soap and cold water. Do not use harsh detergents or bleach.
• Air Dry: Hang the vest to air dry completely. Do not tumble dry or iron.
• Spot Clean: For minor dirt, spot clean with a damp cloth.

7. Troubleshooting

• Vest Bounces During Activity:

  Solution: Ensure all straps (chest and side) are adjusted snugly. The vest should fit close to your body. If the bladder is not full, air can cause sloshing; try to remove excess air from the bladder after filling.
• Chafing:

  Solution: Re-adjust straps to ensure a proper fit. The vest should not be too tight or too loose. Ensure your clothing underneath is appropriate for activity and does not bunch up.

• Bladder Leaks:

  Solution: Check that the bladder cap is securely tightened. Inspect the hose connection points to the bladder and bite valve for any looseness. Ensure the bite valve is not damaged and is properly sealed when not in use.

• Difficulty Drinking from Bite Valve:

  Solution: Ensure the bite valve is not clogged. Gently bite down on the valve while sucking. Check if the hose is kinked or pinched inside the vest.
