They say babies grow out of outfits quickly, but my son has had this outfit for over a year. It's amazing! The first picture was taken when he was 11 months old, on a camping trip with Daddy. The pants were rolled up and the hood nearly covered his whole face. The second picture was taken a little over a month ago, right before he turned two. No need for rolling up, and his head has grown significantly. I think he's finally growing out of it, but I'm impressed with how long it's lasted.
