It does not let any water in, it is indeed waterproof. I tested it during last week's heavy rain while doing deliveries and it stayed dry all day. However, it fogs up a lot and you can't do your job properly. Even though no water gets in, not even a drop, when you open it and put your phone inside, it closes due to the temperature difference and you can hardly see anything in rainy weather. The zipper pulls, at best, I would describe them as funny. They both broke on the second day for no reason and without applying much force. I had to replace them with improvised ones from tir wrap. Also, it can't handle the weight on the pocο χ3 pro, which is not even that heavy, and it keeps bending. It's frustrating and you can't hold it in the position you want to see well and steadily at the right angle. In summary, I would not buy it again for any reason. It is very cheaply made. It's better for anyone who needs it for professional use, such as delivery, to spend 40-50 euros to get one that is worth it.
