That’s what it promises, a mostly waterproof bag with a window. Choosing a size is a bit tricky when sizes go the way it hurts. This is larger than the passport maybe the size of the A5 but the A5 will not fit in due to the drawbar. I carry the passport and papers here so it is very good to use it instead of a closed cordura bag.
The product seems to be of high quality and durable.
Good quality, finally a sturdy "zip loc"!
The water stays outside, the electronics inside and sees what’s in your pocket. Perfect! The touch screen works through the window.
