This is beyond adorable and my son only got to wear it twice before outgrowing it! It is incredibly well made and warm. Lots of details like fleece lined pockets, boot hooks, cuff/sleeve Velcro. Size 4-5. One piece avoids getting snow in their clothes, and having a jacket ride up. Bright green and details along the hood and back make it easy to spot your kiddo on the slopes or sledding hill.
