Runs large!

  • Familiarity:I've put it through the wringer

They're nice, but the bottoms sizing was way off for us. We've a slimmer baby than some it seems! For a 2-year old, size 12M in the bottoms and 18M in the tops was perfect (18M bottoms slipped off, larger around the waist than the Patagonia 2T Puff Pants!) The sizing really seemed surprising (and I was comparing 2 each of each size). I would've preferred 18M leg length with 12M waist size. The new 2013 versions of these are great though, very warm, soft, and washable :)
