Here is a waterproof backpack that holds your camera and drone and keeps your gear protected from the elements. The Inrigo backpacks alert you via Bluetooth if unsafe levels of moisture are detected. They are made of industrial grade material to keep the water out.
The Inrigo ProPak holds two cameras and multiple lenses. It floats and has a valve to let you pump air into it. These backpacks let you carry your drone and tripod around conveniently.
