Snowsuit for Kids - How to Choose the Right One for Winter

A good snowsuit is perhaps the single most important garment your child needs during winter. The right snowsuit makes the difference between a baby who enjoys time outdoors in freezing temperatures and one who's crying from the cold after five minutes.

But the selection is enormous, and it can be hard to know what to look for. This guide helps you choose the right snowsuit for winter -- whether you have a newborn in a stroller or a toddler who wants to play in the snow.

Three Types of Snowsuits - Which One Fits Your Child?

Snowsuits come in three main categories, and each has its strengths. Which type works best depends on your child's age and activity level.

Down Snowsuit

Down is nature's best insulation material. A down snowsuit provides fantastic warmth relative to its weight, making it ideal for babies in strollers or carriers. Down compresses easily and gives the child good freedom of movement.

The downside is that down loses its insulating ability when wet. A down snowsuit is therefore best suited for cold, dry days -- not for playing in slushy conditions.

Synthetic Snowsuit

Synthetic insulation (like PrimaLoft, Thermolite, or Polartec) keeps warm even when damp. This makes synthetic suits more versatile than down -- they handle snow, mud, and rain showers.

Synthetic snowsuits are often cheaper than down, easier to wash, and dry faster. For daycare use, this is the safest choice.

Fleece-Lined Snowsuit

Fleece-lined snowsuits are thinner and more flexible. They work best as a mid-layer or as outerwear on mild winter days (down to about 23°F / -5°C).

The advantage is that the child can move freely. The disadvantage is that fleece alone won't keep them warm in real cold.

How to Choose the Right Snowsuit

Waterproof Rating - How Waterproof Is the Suit?

The waterproof rating tells you how much water pressure the fabric can withstand before water seeps through. For snowsuits, we recommend:

• 3,000 mm - Sufficient for stroller use and short outings
• 5,000 mm - Good for active kids playing in the snow
• 10,000 mm+ - Handles heavy use in wet snow conditions

For daycare, choose at least 5,000 mm waterproof rating. Kids sit in the snow, roll around, and play -- the suit gets exposed to far more moisture than you'd expect.

Breathability

A suit that doesn't breathe causes sweating and discomfort. Look for a breathability rating (MVTR) of at least 3,000 g/m²/24h. The higher the number, the better moisture escapes.

Reflective Details

In winter, daylight hours are short in many regions. Choose a snowsuit with reflective elements on the arms, legs, and back. Many Scandinavian brands have reflective details integrated into the design.

Sizing - Buy Slightly Roomy

A snowsuit should have room for wool layers underneath without being tight. As a rule of thumb, choose one size up from your child's regular clothing size.

For example: If your child usually wears size 80 (12 months), choose a snowsuit in size 86 (18 months). This also leaves room for extra layers on the coldest days.

Many snowsuits have fold-over cuffs on the arms and legs that can be unfolded for extra length. This can give you an extra season with the suit.

Snowsuits by Age

0-6 Months - Stroller Baby

Babies lying in a stroller need lots of insulation because they're not moving. A stroller footmuff or down snowsuit with high fill power is the best choice. Combine with layering underneath.

Look for suits with integrated mittens and foot covers, or use separate accessories. Babies lose a lot of heat through their hands and feet.

6-12 Months - The Crawler

The baby starts moving more and needs a suit that allows freedom. Choose a softer suit with good arm mobility. Synthetic insulation is a good choice because the baby is starting to explore the snow.

1-3 Years - The Active One

Toddlers run, climb, and roll in the snow. Here you need a durable suit with reinforced knees and seat. A waterproof rating of at least 5,000 mm is important, and the suit should handle frequent washing.

When Should You Buy a Snowsuit?

The start of the season is the best time. New winter collections typically arrive in August-September. That's when you have the largest selection and can try it on the child while the weather is still comfortable.

If you wait until November, you risk popular models and sizes being sold out. Many parents buy snowsuits as early as late summer.

January sales can offer great deals, but only if you're buying for next season in a larger size. Remember to account for growth.

Washing and Care

Proper care significantly extends the lifespan of a snowsuit:

• Synthetic suit: Wash at 104°F (40°C) with regular detergent. Tumble dry on low heat or hang to dry.
• Down suit: Use a down-specific detergent. Wash at 86°F (30°C). Tumble dry with tennis balls to help the down loft back up.
• Reproofing: Re-waterproof the suit once per season with spray or wash-in treatment. This maintains the water repellency.

Close all zippers and velcro before washing. Wash the suit inside out. Avoid fabric softener -- it can destroy water-repellent properties.

Layering Under a Snowsuit

A snowsuit alone won't keep your child warm. What's underneath matters just as much. Here's a simple setup:

Layer 1 (base): Wool bodysuit and wool pants close to the skin. Merino wool is soft and regulates moisture. Read more in our layering guide.

Layer 2 (mid): Wool sweater or fleece. In extreme cold (below 14°F / -10°C), add an extra wool layer.

Layer 3 (outer): Snowsuit.

Accessories: Wool hat, wool mittens, and warm boots. Remember that children lose a lot of heat through their heads.

Safety Tips for Snowsuits

• Car seat and snowsuit: Thick snowsuits can prevent the car seat harness from fitting snugly enough. Remove the suit in the car and use a blanket over the child instead.
• No hood drawstrings: Choose models without loose cords that can get caught.
• Reflective gear: Make sure the child is clearly visible in the dark. An extra reflective vest over the suit is smart.
• Check the temperature: Babies can overheat indoors wearing a snowsuit. Remove the suit as soon as you come inside.

Frequently Asked Questions About Snowsuits for Kids

What is the best snowsuit for children?

Reima, Polarn O. Pyret, and Didriksons consistently score high in Nordic tests. The best choice depends on your child's age and use. For daycare, durable models with high waterproof ratings are recommended, while down snowsuits are best for stroller babies who need maximum warmth without weight.

How many snowsuits does my child need?

Most families manage with one snowsuit per season. If your child goes to daycare, it can be smart to have two -- one in use and one drying. Alternatively, you can have one good snowsuit and supplement with a thinner jacket for milder days.

When is my child too big for a snowsuit?

One-piece snowsuits are typically used up to age 4-5. After that, most children switch to a two-piece set with jacket and snow pants. Some children prefer two-piece suits from age 3 because it's easier to use the bathroom.

Can my baby wear a snowsuit in the car seat?

No, thick snowsuits should be removed in the car seat. The thick material prevents the car seat harness from tightening properly, and the child could slide out in a crash. Use a blanket or thin fleece suit instead, and put the snowsuit on afterward.

What's the difference between 3,000 mm and 10,000 mm waterproofing?

The waterproof rating measures how much water pressure the fabric can withstand. 3,000 mm is sufficient for light snow and stroller use. 5,000 mm handles a child sitting in wet snow. 10,000 mm is nearly fully waterproof and handles the most demanding conditions. For daycare, at least 5,000 mm is recommended.
