Mandatory In Many Places
Helmet use for children is a legal requirement in several alpine regions and is effectively universal practice everywhere else.
Ski schools and children's lessons generally require one, and hire shops include them as standard with children's equipment.
That means the question is which helmet rather than whether, which simplifies the decision considerably.
Never Buy To Grow Into
A helmet that is loose moves on impact and can shift off the area it was protecting, which means a helmet bought a size large protects worse than one that fits.
Children grow and a helmet will be outgrown, which is an annual cost rather than a reason to buy large.
Adjustable retention systems extend the usable range somewhat and do not turn a helmet two sizes too big into one that fits.
Fit Checks For Children
The helmet should sit level with the brim just above the eyebrows, not tipped back exposing the forehead, which is the commonest error.
It should not rock forward and back or side to side, and should stay in place when the child shakes their head with the strap undone.
A child who says it is uncomfortable will resist wearing it, which makes comfort a safety consideration rather than a luxury.
Goggles, Gaps And Cold
A gap between the goggle top and the helmet brim exposes a child's forehead to cold and wind, which is both uncomfortable and a frostnip risk.
Buying goggles and helmet together, or checking compatibility, avoids a gap that a child cannot fix themselves on a lift.
Goggles should be worn under the helmet strap arrangement correctly, and a child pushing goggles onto their forehead loses the seal entirely.
Second Hand And Unknown History
A helmet that has taken an impact is spent even when it looks perfect, and a second-hand helmet carries an unknown impact history.
That makes used helmets a poor economy for children specifically, since the whole point is protection whose condition cannot be verified.
Hiring for a week, or buying new each season, both avoid the problem entirely.
Weight matters more for children than adults, since a heavy helmet on a small neck becomes tiring across a full day and a tired child stops enjoying skiing. Lighter junior helmets cost more and the difference is genuinely felt by the person wearing it. Checking weight alongside fit is worth doing, since it is rarely prominent in product descriptions and affects whether the helmet is worn willingly.
Bright colours help a parent keep track of a child on a crowded slope, which is a practical benefit entirely separate from protection and costs nothing to choose.
Chin strap padding matters for whether a child complains, since a thin strap under the jaw becomes uncomfortable within an hour and comfort determines whether it stays on.
The Verdict
Non-negotiable equipment where correct current fit matters far more than anything else, and where used purchases are a poor idea.
Helmets bought large protect worse, second-hand history is unknown, and gaps at the brim cause cold and frostnip.
Never buy a size up to last. A loose helmet moves on impact and protects the wrong part of the head.

- Second-hand impact history is unknowable
- Gaps at the brim expose the forehead
Frequently asked questions
Can I buy a size up to last two seasons?
No. A loose helmet moves on impact and can shift off the area it was protecting, so it protects worse than one that fits. Adjustable retention extends the range somewhat but not across two sizes.
Is second hand acceptable?
Not really. A helmet that has taken an impact is spent even when it looks perfect, and a used helmet carries unknown history. Hiring for the week or buying new each season avoids the problem entirely.
How do I check the fit?
Level, with the brim just above the eyebrows rather than tipped back. It should not rock in any direction and should stay put when the child shakes their head with the strap undone. Comfort matters too — they will resist an uncomfortable helmet.

The bottom line
Fit it to the head they have now. Buying large to last means it protects the wrong part of the head.
