Nalgene and Marvel have come together to battle the greatest threat to
mankind yet - thirst! This leakproof BPA free water bottle is tougher
than The Incredible Hulk, The Mighty Thor, and the Invincible Iron Man
Perfect for little hands, and tough enough to survive being thrown from a moving minivan. Features:
Good size, easy to carry and my 4 yr loves it. That said it didn't get a 5 because it can be tricky to close for little hands. Do like that it DOESN'T haven't pieces that are hard to clean where mold tends to hide with other bottles.
