We used to sell a seat bag made of polyester, and we had a 68-years-old user who had retired and often rode in the wild with his wife. The weather was pretty good at the beginning, but it suddenly started to rain heavily when they passed by a forest . Although they eventually found the shelter, the seat bag was still wet and the phone inside was ruined. All of the nice pictures about the journey can not got back on the phone. We feel very sorry after reading the grandfather's experience, so I decided to make a fully waterproof seat bag .
