Quick answer: For most kids, a neck warmer is the everyday choice and a balaclava is for the coldest, windiest days. The Canadian Paediatric Society tells parents to "use a neck warmer instead of a scarf" for children. Pick a balaclava when cheeks, ears and neck all need covering at once, and keep scarves for calm walks with older kids.
Scarf, neck warmer or full-head balaclava? Each one covers a different amount of skin, suits a different age and works differently under a snowsuit hood. This guide compares all three using what Canadian and American pediatric sources say about neck coverings and cold weather.

What Is the Difference Between a Neck Warmer, a Scarf and a Balaclava?
The difference is how much skin each one covers and how it stays on. A neck warmer is a closed tube around the neck. A scarf is a loose strip of fabric you wrap and tie. A balaclava is a fitted hood that covers the head, ears and neck and leaves only the face open.
What is a neck warmer?
A neck warmer (also called a neck gaiter) is a short, closed loop of fleece, knit or jersey that slips over the head and sits around the neck. Because it has no loose ends, there's nothing to untie, trail behind or come loose during play. Many styles can be pulled up over the chin or nose when the wind picks up, then pushed back down. Some, like turtle-style neck warmers, add a bib-shaped panel at the front that tucks inside a jacket to block drafts at the zipper.
What is a balaclava?
A balaclava is a stretchy hood that covers the top of the head, the ears, the sides of the face and the neck in one piece. The face opening is usually large enough to show the eyes, nose and mouth, and on some styles the lower edge can be pulled up over the chin. Kids can wear it alone on cold days or under a toque (hat) and a snowsuit hood when it's bitterly cold.
What is a scarf?
A scarf is a long, flat piece of fabric wrapped around the neck and tied or tucked. Scarves are flexible and easy to style, but they rely on a knot or a tuck to stay in place, and the ends hang free. That loose design is exactly why pediatric guidance points parents toward neck warmers for young children, as the next section explains.
| Feature | Neck warmer | Balaclava | Scarf |
|---|---|---|---|
| What it covers | Neck; can pull up over chin or nose | Head, ears, neck and sides of the face | Neck; partial face if wrapped high |
| Loose ends | None | None | Yes |
| Stays in place during play | Yes, stretches to fit | Yes, fitted hood | Can loosen or unwrap |
| Easy for kids to put on alone | Very easy (pull over head) | Easy once they can pull on a hood | Harder (needs wrapping or tying) |
| Typical use | Daily school runs, recess, daycare | Very cold or windy days, long outings | Calm walks for older kids |
| Works under a snowsuit hood | Yes | Yes, replaces a hat on the coldest days | Bulky under a zipped collar |
Why Do Canadian Pediatricians Recommend a Neck Warmer Over a Scarf?
Because a scarf's loose fabric can be a choking risk for children. The Canadian Paediatric Society's Caring for Kids winter guidance says it plainly: "Use a neck warmer instead of a scarf, and mitten clips instead of a string to prevent choking."
The same CPS list advises parents to remove drawstrings from younger children's clothing "that could catch on climbing or play equipment" and to use Velcro or snaps instead. The common thread is simple: anything long and loose around a child's neck can get caught or pulled during active play. A kids' neck warmer covers the same area with no ends to catch.
That doesn't mean a scarf is never an option. For an older child walking to the store with you, a scarf tucked inside a zipped coat is a different situation from a preschooler climbing a play structure at recess. The practical rule many families follow: neck warmer for play, daycare and school; scarf only for calm, supervised outings with older kids, and always swap it for a neck warmer before playground time.
Balaclava vs. Neck Warmer for Kids: Which Covers More?
A balaclava covers more. It wraps the head, ears, neck and the sides of the face in one layer, while a neck warmer covers only the neck and, when pulled up, the chin and lower face. The right pick depends on how cold and windy it is and how long your child will be outside.
Coverage matters most for the parts of the body that freeze first. The American Academy of Pediatrics' HealthyChildren.org winter guidance notes that "Fingers, toes, ears, and noses are most likely to get frostbite." The CPS adds that children should "Always keep ears covered to prevent frostbite."
Here's how that plays out in real life:
- Neck warmer plus hat. This combination covers the neck and ears and leaves the face open. It suits most school days, daycare outings and short trips outside. It's also easier to adjust: if your child warms up while sledding, the neck warmer can slide down without removing the hat.
- Balaclava alone or under a hood. One piece covers ears, neck and cheeks, so there's no gap between hat and collar for snow or wind to sneak in. It shines on long outings, windy hills and the coldest mornings at the bus stop.
- Balaclava plus toque. On bitter days, a light hat over the balaclava adds a second layer on top of the head where a hood may not reach.
Comfort is the trade-off. Some kids dislike the snug feel of a balaclava, and they can overheat in one on milder days. Avoid stacking a balaclava, a thick neck warmer and a hood for active play; start with one layer and add if needed.
Which Option Fits Each Age?
The short answer: babies need a hat that covers the ears and a snowsuit hood, with a small baby-sized neck warmer only if it fits well; toddlers and preschoolers do well with a neck warmer they can pull on themselves; and school-age kids can switch between a neck warmer and a balaclava depending on the weather.
Babies (6 to 24 months)
Babies can't tell you they're cold. The CPS notes that "Babies need extra care and bundling because they cannot generate body heat or tell you if they are cold the way an older child can." For most outings, a warm hat that covers the ears, and a snowsuit or bunting with the hood up do most of the work.
If you want extra coverage at the neck, choose a baby-sized neck warmer with a short, soft collar that doesn't ride up over the mouth. Check it often during the outing, and take it off as soon as you come inside. For hat sizing and indoor rules, see our guide on whether a newborn needs to wear a hat, and remove all neck and head layers before naps and sleep (our winter sleep dressing guide covers what to use instead).
Toddlers and preschoolers (2 to 5 years)
This is neck warmer territory. A simple tube is easy for a two- or three-year-old to pull over their head with a little help, there are no ends to tie, and daycare staff can adjust it in seconds. A toddler balaclava is useful on very cold or windy days, especially for kids who pull their hats off. Because it covers ears and neck in one piece, there's one less item to lose in the cubby.
Look for soft, stretchy fleece and a face opening that sits clear of the eyes.
School-age kids (6 to 12+)
Older kids can manage either option and often have opinions about the look. A neck warmer is the easy everyday pick for recess and the walk to school. A balaclava earns its spot on ski days, outdoor rink nights and long waits at the bus stop. By this age, kids can also learn to pull the neck warmer up over their nose on windy stretches and down again when they're active. Still choosing what goes over it? Our guide to choosing a winter coat or snowsuit for school compares recess setups.
How Cold Is Too Cold, and When Should You Add a Balaclava?
Health and weather authorities draw the line well below freezing. The CPS says to consider keeping children indoors "whenever the temperature or the wind chill is reported to be -27°C (-16°F) or lower," because "At these temperatures, exposed skin will begin to freeze." The AAP gives a similar line: "playing outside in temperatures or wind chills below -15° Fahrenheit should be avoided."
Environment and Climate Change Canada's wind chill guidance lists a moderate risk from -10 to -27, with a "risk of hypothermia and frostbite if outdoors for long periods of time" for kids who aren't dressed for it. From -28 to -39, it warns that "any exposed skin can freeze in 10 to 30 minutes."
Those numbers aren't a dressing chart, but they're a useful guide for when to cover more skin. Here's a practical way many Canadian families use them (always check the wind chill, not just the temperature):
| Wind chill | Official guidance | Practical neck and face layer |
|---|---|---|
| 0 to -9 | ECCC: low risk, "slight increase in physical discomfort" | Light jersey or knit neck warmer, or none |
| -10 to -27 | ECCC: moderate risk on long outings | Fleece neck warmer plus a hat that covers the ears; balaclava for long or windy outings |
| -27 (-16°F) or colder | CPS: consider keeping children indoors; skin begins to freeze | Short trips only, fully covered: balaclava or neck warmer pulled up, hat and hood |
Whatever your child wears, check in often. The CPS advises parents to "Check often to see that your child is warm and dry," and the AAP recommends regular indoor breaks to warm up.
How Do You Wear a Neck Warmer or Balaclava With a Snowsuit Hood?
Put the neck or head layer on before the jacket, tuck it under the collar, then zip up and pull the hood over the top. This order keeps snow out of the gap at the neck and lets the jacket's collar hold everything in place.
Step by step:
- Base and middle layers first. Dress your child in their base layer and a warm middle layer. Our 3-layer guide for kids explains what goes where.
- Neck warmer or balaclava next. Pull it over the head. For a neck warmer with a bib, smooth the bib flat against the chest. For a balaclava, line up the face opening so it sits clear of the eyes.
- Snow pants or the snowsuit. Step into the suit and pull it up to the chest.
- Jacket over the top. Zip the jacket all the way up so the collar sits over the bottom edge of the neck warmer or balaclava. Fold the chin guard down if the jacket has one.
- Hat, then hood. Add a hat if needed (a toque over a balaclava on very cold days), then pull up the hood.
- Mittens last. Tuck mitten cuffs under or over the jacket cuffs so wrists stay covered.
Two small tips make a big difference. First, check that the hood still lets your child turn their head and see to the sides; a thick balaclava plus a big hat can push a hood forward. Second, if your child will be very active, start with the neck warmer pulled down. They can pull it up once they slow down or the wind picks up.
Some Deux par Deux snowsuits include a neck warmer in the box. Deux par Deux lists a "polar fleece neckwarmer" as included with some PLAY snowsuits, such as its Two Piece Play Snowsuit Mint Green and Kids One Piece Play Snowsuit Gray And Blue Dinosaur Print, so check the product details before you buy an extra one. For help choosing the suit itself, see our snowsuit sizing guide.
How Should a Kids' Neck Warmer or Toddler Balaclava Fit?
It should be snug enough to stay in place without pressing on the throat, and loose enough for your child to turn their head and talk comfortably. Run through this quick check the first time they wear it:
- The two-finger test. You should be able to slide two fingers between the neck warmer and your child's neck.
- Clear view. A balaclava's face opening should sit around the eyes, not over them. Have your child look up, down and side to side.
- Easy breathing. When pulled up, the fabric should rest lightly over the nose and mouth, not pull tight. If it gets wet from breath, it's time to pull it down or swap it.
- Stays put. Ask your child to jump and wave their arms. A good fit doesn't slip over the eyes or ride up over the mouth. Take it off as soon as you come inside.
- Room under the hood. Put the snowsuit hood on over the top and check that it still sits comfortably.
Sizing on kids' neck warmers and balaclavas is usually by age range, such as 2/6 or 7/14. If your child is between ranges, go by head size and comfort. A neck warmer that is too big will slip; one that is too small will feel tight at the neck and be hard to pull over the head.
Which Fabric Should You Choose: Fleece, Knit or Jersey?
Polar fleece is the go-to for cold days, knit adds a classic look and extra loft, and lightweight jersey suits fall and spring. Here's how they compare using the materials brands list on their product pages:
- Polar fleece. Soft and warm. Deux par Deux lists its Polar Fleece Neckwarmer as 94% polyester and 6% elastane, and its Stretchy Polar Balaclava uses the same blend, which gives the stretch that helps them stay put.
- Knit. Cozy and classic, often paired with a fleece lining. Deux par Deux lists a 100% acrylic collar on its Knit & Polar Turtle Neckwarmer, with a polyester and elastane fleece bib underneath.
- Plush fleece. Extra-soft and fuzzy. The Deux par Deux Plush Balaclava is listed as 100% polyester plush fleece.
- Jersey. Thin and stretchy, a good choice for the first frosty mornings. Deux par Deux lists its Jersey Neck Tube as a polyester jersey in sizes 2/6 and 7/14.
For the coldest days, fleece or a knit-and-fleece combination is the warmer choice. For fall, mild winter days or kids who run hot, a jersey neck warmer is lighter and less likely to make them sweat. The CPS reminds parents that "If your child is dressed too warm, they could sweat and feel colder when they stop playing."

How Do You Wash and Dry Neck Warmers and Balaclavas?
Follow the care label, wash cold, and make sure each piece is completely dry before the next outing. Neck warmers and balaclavas get damp from breath, snow and runny noses, so they need washing more often than a jacket.
- Check the label first. Care differs by fabric. Deux par Deux lists "Machine wash cold, tumble dry low" for its Polar Fleece Neckwarmer, while its knit-and-fleece styles call for a cold delicate cycle with no tumble drying.
- Skip fabric softener on fleece. Deux par Deux lists "no fabric softener" in the care instructions for its polar fleece neck warmer.
- Dry fully between uses. A damp neck warmer feels cold against the skin. Hang it to dry at room temperature (Deux par Deux lists "keep away from direct heat" for its polar fleece neck warmer), or rotate between two so one is always dry.
- Change wet gear right away. The CPS advises parents to "Remove wet clothing and boots immediately after playing," and the AAP says to "Make sure children change out of any wet clothes right away." A spare neck warmer in the backpack makes that easy at school.

Frequently Asked Questions
Is a neck warmer better than a scarf for kids?
For play, school and daycare, yes. The Canadian Paediatric Society advises parents to "Use a neck warmer instead of a scarf, and mitten clips instead of a string to prevent choking." A neck warmer has no loose ends and stays in place.
What is the difference between a balaclava and a neck warmer?
A balaclava covers the head, ears, neck and sides of the face in one piece and leaves the face open. A neck warmer covers only the neck and can be pulled up over the chin or nose. Kids wear a hat with a neck warmer to cover their ears.
At what age can a toddler wear a balaclava?
The Deux par Deux kids' balaclavas we carry come in sizes from 2/4 or 2/6, and the brand also makes baby balaclavas in size 6/24m. Choose one sized for your child's head, check that the face opening sits clear of the eyes, and stay nearby so you can adjust it. For babies, a hat that covers the ears and a snowsuit hood usually work better.
Can a baby wear a neck warmer?
A baby-sized neck warmer can add warmth outdoors if it fits well and doesn't ride up over the mouth. Check it often during the outing and take it off as soon as you come inside and before naps or sleep.
When should my child wear a balaclava instead of a neck warmer?
Choose a balaclava on very cold or windy days and for long outings, when ears, cheeks and neck all need covering. Environment Canada warns that from -28 to -39 wind chill, exposed skin can freeze in 10 to 30 minutes.
How cold is too cold for kids to play outside?
The CPS suggests considering keeping children indoors when the temperature or wind chill is -27°C (-16°F) or lower. The AAP says playing outside in temperatures or wind chills below -15°F should be avoided.
Should a neck warmer go under or over the snowsuit?
Under the jacket collar. Put the neck warmer or balaclava on first, zip the jacket up over its bottom edge, then pull the hood over the top. This keeps snow and wind out of the gap at the neck.
Bottom Line
For most kids, most of the time, a neck warmer is the simple, everyday answer: it has no loose ends, it's easy to pull on, and it follows the Canadian Paediatric Society's advice to choose a neck warmer instead of a scarf. Add a hat to cover the ears, and switch to a balaclava when the wind chill drops or your child will be out for a long time. Keep scarves for calm walks with older kids, check the fit, and take every layer off as soon as you come inside.
