Bunkers and shield (especially inflatable [easy to pack away]) aren't exactly bad ideas, but from the images they don't look that good at all. Why all the holes? I understand why you might have one hole, to fire your blaster through, but 5 (on the shield) or more (on the 'bunker')? Besides, the 'bunker' is too small to be a bunker, it's just a larger shield.
They probably work well against the burst/bolt or the foam dart though, and probably of more use in the pool. Actually, if you only think of them as summer pool toys, these are all probably pretty good fun (except you wouldn't want to use most of the current NERF blasters in a pool [making the shield holes useless]

).
Haven't seen the goggles anywhere online. Look any good? If they're just normal NERF ones, they might not be too bad. They could just be NERF swim goggles though (would make sense with the pool theme).
EDIT:
No sign of them over here. Shame really, they might have been fun to use in the pool on holiday. Four bunkers mounted to the inflatable boat... with a shield roof... to make a water tank.
I guess I'll just have to live with turning my boat upside down... again.
I am such a child.
