Snowsuit, jumpsuit, ski wear type one-piece! Great for playing in the snow and playing outside!! The leg parts have a double structure, so you can put the nylon part inside and wear snow boots, and then cover the snow boots to prevent snow from entering from the feet! You can also adjust the length of the arms and legs by adjusting the strings in the pockets and the strings on the sides. It is designed to be worn over clothes and is made to be a bit oversized, so we recommend a size that fits just right.
