One-Piece Snowsuits

(67 products)

Babies from 3 months and kids up to size 16 stay covered from hood to ankle in a one-piece snowsuit, with no waist gap for snow during sledding, recess or a first ski lesson. Deux par Deux makes nearly all of these suits for girls and boys, and Nano adds one more.

For toddlers and school kids, Deux par Deux winter outerwear gives its PLAY one-pieces (sizes 2 to 14) and DISCOVER one-pieces (sizes 2 to 8) a -30°C rating. Ski days call for the Deux par Deux TEKNIK ski line: its one-piece suits run from size 4 to 16, and the brand pairs a 15,000 mm shell with a PrimaLoft® hood rated to -30°C. Several baby one-pieces, sized 3 months to 30 months/2T, carry the brand's adapted-for-car-seats label and sit together under car seat snowsuits and jackets, although the seat maker's instructions on winter clothing still come first. Nano contributes the Raya, a girls' one-piece in 2Y to 8Y that the brand rates to -30°C, alongside its other Nano kids' snowsuits.

Families who want separates can switch to two-piece snowsuits with a removable jacket. Baby shoppers can narrow the list with baby girls' snowsuits or baby boys' snowsuits, while kids' base layers go underneath and kids' mittens and gloves cover small hands.

One-Piece Snowsuits FAQ

One-piece or two-piece snowsuit: which is better?

A one-piece has no waist gap, so snow stays out when little ones sit or roll in it. A two-piece lets the jacket come off indoors and the pants fit separately. Many parents choose one-piece for babies and toddlers and two-piece snowsuits for school-age kids.

How warm are these one-piece snowsuits?

Warmth depends on the line, so check each product page. For example, Deux par Deux lists its PLAY one-piece suits as rated to -30°C (-22°F), and the Nano Raya one-piece is also listed with a -30°C rating.

What sizes do one-piece snowsuits come in?

Baby styles start at 3 to 6 months and run to about 30 months or 2T, and kids styles from Deux par Deux run from 2 up to 16 in some lines. Compare your child's height with the brand size chart, and leave room for a base layer.

Can a one-piece snowsuit be worn in a car seat?

Some baby styles are made for car seats, and you'll find them in car seat snowsuits and jackets. Always follow your car seat manufacturer's guidance on winter clothing.
