Design Waterproof Car Roof Cargo Bag

Job ID: 40607458

Budget: $700 – $1,000 USD

This is a 21 Cubic feet car roof cargo bag. I already have a mature existing product. My only requirements are the following three points:
1. Optimize the waterproof treatment at the stitched seams. The current manufacturing process is sewing, and the production process will not be changed.
2. Improve the zipper waterproof protection to completely isolate the zipper from water exposure.
3. A more appealing exterior design tailored to the American market.
