The bag is made from extremely light ripstop fabric make it a great companion for long kayak trips or hikes. All seems are taped preventing water from getting in. And air coming out - so lock some air in and use it as a pillow.
The bag is moist proof. Water will get in under excessive amount of pressure. Avoid storing electronics when jumping off a sinking ship into a stormy ocean.
