Setup and Sealing Instructions
Properly sealing your dry bag is crucial to ensure its waterproof performance. Follow these steps carefully:
- Step 1: Prepare the Opening
Tuck the top opening of the bag neatly. - Step 2: Fold Down
Fold the top opening down 3 to 4 times. Ensure each fold is tight and even. - Step 3: Secure Side Buckles
Fully fasten the bag's side buckles and side clips to secure the rolled-down top. Repeat this on both sides. - Step 4: Fasten Top Buckle
Finally, snap the top clip into place to complete the installation and create a secure, waterproof seal.

Important: Before placing valuable items inside, perform a waterproof test by filling the bag with air, sealing it, and submerging it in water to check for any leaks.
Operating Instructions
Dry and Wet Separation Design
The backpack features a built-in dry and wet separation bag. This allows you to store wet items (like outdoor wet clothes or umbrellas) separately from dry items (such as electronic devices, documents, and other essentials) to prevent them from getting wet.

External Storage and Pockets
- Elastic Webbing: The front of the bag features elastic webbing that can be used to securely hold items like shoes or other gear for easy access.
- Side Mesh Pockets: Both sides of the backpack are equipped with mesh pockets, ideal for holding water bottles, soft water bags, or other small items. The rubber band at the mouth of the pocket helps secure items and reduce shaking.
