waterproof bag custom

By deeply understanding your brand’s style and target audience, we design and develop products, and ultimately create waterproof bags that showcase the brand’s personality and outstanding performance.

Do you support customizing the size and functions?

We offer customization options for size, color, logo, pocket layout, shoulder strap design, and more. Additionally, special features such as USB charging ports and reflective strips can also be added.

Can a waterproof bag completely prevent water from entering?

Our waterproof bag has passed the IPX7 certification and remains watertight when submerged in 1 meter of water for 30 minutes. However, it is recommended to avoid prolonged underwater use. Make sure the zipper is fully closed.

For which usage scenarios is it suitable?

Outdoor sports, maritime operations, military protection, medical emergency response, and other scenarios can all be customized to meet different environmental requirements.

What's the difference between a regular waterproof bag and an all-purpose waterproof bag?

All-purpose waterproof bag: It can withstand heavy rain erosion or float on water for a period of time. It is highly suitable for any water-related activities (rafting, kayaking, swimming, etc.) and internal waterproofing. The material is wear-resistant and tear-resistant. It keeps your items dry at all times during water activities.

Regular waterproof bag: Usually only suitable for light water exposure in daily life, such as water repellency and small rain. Regular waterproof bags often use nylon material, with needle sewing at the seams and sealing strips for internal waterproof reinforcement. However, even so, the waterproof strength is far less than that of the dry bag’s waterproof mechanism.
