Backpack Care Guide
Washing
- Before first use and for regular cleaning, wash with clean water and a mild soap or detergent. Do not use bleach.
- Clean with mild soap or detergent only. Do not rinse with bleach.
- Gently brush with a soft-bristle brush to avoid damaging the waterproof coating.
- Use a mild or slightly acidic detergent and rinse thoroughly to minimize chemical residue.
- Do not soak for extended periods, as prolonged immersion may reduce waterproof performance.
- After washing, air dry in a cool, well-ventilated area. Avoid direct sunlight to prevent premature aging of the waterproof layer.
- Spot clean with a damp cloth as needed.
