Don't expect diving with it, nor waterproofness. But it is one great water resisting, perfectly padded sleeve.
Using the iPad through the transparent side of it works perfectly even if your hand is somewhat wet. The back of it is very well padded, has a pocket to eventualy stow away the earbuds and a strap through which you could slip your hand and hold the iPad so as not to drop it.
