O'Neill Moonstone Snow Suit
Here's what other sites are saying:
Rather than fuss with a separate ski jacket and ski pants, the O'Neil Toddler Girls' Moonstone Snow Suit combines the top and bottom and keeps her protected from the elements with waterproof fabric and a touch of synthetic insulation. Instead of draining your wallet of all her college-fund money, the Moonstone fends off the soggyness of wet lift rides, and fights the bitterness of cold days so you can stay out longer. O'Neil gave this suit a 'grow' construction, which allows you to get a little bit of extra room out of the arms and legs as she gets larger, rather than buying a new suit every season.
