Bag is very high quality, waterproof material. The main compartment can be with clip and / or zipper closure. That means you can either select the shortcut or the dust and rain waterproof option. In closing the main compartment is a small mesh compartment for an SD card and put forward is a compartment for batteries, battery, coins etc. More needs it then for a bridge cam also not more. And that for the price I think is unbeatable.
