1. Ergonomic Design of the Carrying System

The carrying system is the part of the waterproof bag that directly contacts the user, and its design directly affects wearing comfort. To accommodate users of different body types, the carrying system should have the following features:

• Adjustable shoulder straps: Ensure that the straps can be adjusted according to the user's height and physique, distributing the weight of the bag and reducing shoulder pressure.

• Waist belt support: By using a waist belt, the weight of the bag is transferred to the hips, alleviating the burden on the shoulders and back.

• Breathable back padding: Utilizing breathable materials and a mesh structure ensures ventilation for the back, reducing sweat accumulation.

2. Weight Distribution and Ergonomics

Proper weight distribution ensures the stability of the bag and reduces user fatigue. Design considerations include:

• Low center of gravity design: Place the heavier items at the bottom and close to the back to enhance stability.

• Multiple compartments and pockets: Allows users to categorize items and balance weight distribution.

3. Ergonomics and the Opening System

To enable users to quickly access items, the opening system of the waterproof bag should also consider ergonomic design:

• Easy-to-operate zippers: Considering the use of gloves in outdoor environments, zippers should be large and easy to grasp.

• Quick buckle system: Allows users to access items quickly without having to remove the bag.
