Toddler & Kids' Snowsuits

Why a One-Piece Snowsuit Wins the Snow Day

For a child who spends the day sitting, crawling and sliding, a one-piece is the simplest thing to get on and the least to keep track of. Once kids are older and want to manage their own layers, a jacket with does the same job with more flexibility. Here's what every Reima snow suit gives you:

• 100% waterproof and windproof ReimaTec shell with taped seams - weather stays out

• Warmth-tested to -5°F or below, with recycled Fellex insulation that adds warmth, not bulk

• Room to grow: 2-3 inches of extra length, so one suit lasts more than one winter

• Breathable, so a kid who's been running doesn't end up damp and cold

• Reinforced knees and seat, where snow play is hardest on gear

• Reflective details for short winter afternoons

• Made without added PFAS or other harmful chemicals

• Unisex from 9 months to 10 years, and built to be handed down

Snowsuit Sizes: 9 Months to 10 Years

Reima snowsuits run 9-12M, 12-18M and 18-24M for babies, 2T through 4T for toddlers, and 5Y to 10Y for preschoolers and older kids. If you're shopping for a 5T snowsuit, that's our 5Y.

Layering Under a Snowsuit

A snowsuit is a shell and an insulation layer - what goes underneath decides how long a child lasts outside. Wool is the place to start: it keeps warming even when it is damp, which is why every Reima base layer set is built around merino.

Warmth you can trust, a shell that stays waterproof, and seams that survive a second child. Every Reima suit is warmth-tested before it reaches a store, made without added PFAS, and built solidly enough to go to a younger sibling afterwards.

Frequently Asked Questions

Are Reima snowsuits waterproof?

Yes - 100% waterproof ReimaTec with every seam taped, so melting snow and sleet stay on the outside. Worth checking on any snowsuit you compare: many are only water-repellent, which holds up to dry snow but not to a wet spring day.

Is there a waterproof snowsuit for a baby?

Yes. The range starts at 9-12M, and the smallest sizes use the same waterproof, windproof ReimaTec shell with taped seams as the rest - breathable too, which matters for a baby who is being carried rather than moving. Browse , 9-12M through 3T.

How cold can a Reima snowsuit handle?

All of them are warmth-tested to -5°F or below. That figure assumes a child who is moving and dressed in proper layers underneath - a merino base layer and, in real cold, a fleece on top of it.

Do Reima snowsuits come in 2T, 3T, 4T and 5T?

Yes - 2T, 3T and 4T are all in the range, and a 5T snowsuit is our 5Y. Below that, babies are covered by 9-12M, 12-18M and 18-24M. Every suit is cut with 2-3 inches of growing room, so take your child's usual size rather than buying a year ahead. Height ranges for each size are on the .

Are Reima snowsuits for boys or girls?

Both. Reima snowsuits are unisex: same cut, same fit, same features, and every color open to any child. It's also why a suit can be handed down to whoever comes next.
