Ski Helmet Buying Guide

In-mould, hard shell, or hybrid? The slopes can get busy, and not everything's in your control, so a helmet that fits well and suits how you ski lets you relax and enjoy the day, whatever your ability.

Construction decides how a helmet absorbs an impact, and different builds suit different riding.

In-mould helmets fuse a polycarbonate outer shell to a foam liner in one piece, keeping weight down without giving up protection. They suit long days on the mountain, where a lighter helmet stays comfortable turn after turn.

Hard shell helmets use a separate outer shell over a foam liner. The rigid shell holds up well against sharp impacts, which suits riders spending time in the park or in terrain where a helmet is more likely to hit something hard and specific rather than absorb a broad fall.

Hybrid helmets sit between the two, built to balance the lighter feel of in-mould construction with some of the toughness of a hard shell. They suit most riders who don't fit neatly into either extreme.

Getting the size right starts with an accurate head measurement, not a guess based on the size you wear in a cap.

How to measure:

Wrap a soft tape measure around your head, about 1cm above your eyebrows and ears, across the widest part of your forehead.
Keep the tape level all the way round, not tilted at the back.
Pull it snug, not tight, the way the helmet itself should sit.
Note the measurement in centimetres. Sizes are almost always listed this way.
Add around 1cm if you have thick or long hair, or plan to wear a thin liner underneath.

Sizing varies between brands, so check the specific size chart rather than assuming a number carries across. As a rough guide, women's helmets typically run XS to M (51 to 58cm) and men's M to XXL (57 to 64cm). Children's helmets come in smaller sizes and should be remeasured each season as heads grow.

A helmet that measures right on paper can still sit wrong on your head, so check it properly before buying.

What a good fit feels like:

The front edge sits one to two fingers above your eyebrows, covering the forehead without blocking your view.
It feels snug all the way round, without pressure points or gaps anywhere.
There's no space between the liner and your scalp. Shake your head and the helmet moves with you rather than shifting on its own.
The chin strap sits secure but not tight, with room for one or two fingers between strap and chin.
Worn with your goggles, there's no gap between helmet and goggle rim, and no pressure pushing down on the bridge of your nose.

A helmet that's too loose can move during a fall, which cuts into how well it protects you. One that's too tight causes headaches over a day, which is its own kind of distraction on the slopes. If you feel pressure points anywhere, try a different size or a different shape before assuming the fit is close enough.

Small details decide how much a helmet gets used rather than left in a bag.

Adjustable vents let you regulate temperature rather than overheating on a warm day or a hard climb.

A dial or adjustable band at the back lets you fine tune the fit without needing a different size.

Check the helmet's shape against your goggles specifically, since a mismatch leaves a gap that lets in cold air and snow.

These come out for washing and swapping between a warmer or cooler setup depending on conditions.

Some helmets build in space for speakers or a Bluetooth setup, useful if you like music or need to stay in contact on the slopes.

Look for a recognised standard such as CE EN1077 for the European market, which confirms the helmet has been tested rather than just styled to look protective.

A lighter helmet cuts down on fatigue over a full day, which matters most for children or anyone who prefers a minimal feel. Weight is worth trading off last, after fit and certification are already settled.

Type (in-mould, hard shell, hybrid or full-face) matches how and where you ride
Measured head size checked against the specific brand's size chart
Front edge, snugness, and chin strap all checked in person, ideally with your goggles
MIPS included, if you want the extra protection against angled impacts
Safety certification (such as CE EN1077) confirmed on the label

MIPS (Multi-directional Impact Protection System) targets a kind of impact a standard helmet doesn't fully address.

Most helmets absorb impacts that come straight on well. Real falls are often angled instead, and an angled impact creates rotational force that twists the brain inside the skull, which is a common cause of concussion. MIPS adds a low-friction layer, usually a distinct yellow liner, between the outer shell and the inner padding. On an angled impact, that layer lets the helmet rotate slightly against the head, around 10 to 15mm, redirecting rotational force away from the brain instead of transferring all of it.

It adds only a small amount of weight, and independent testing shows a meaningful reduction in rotational force depending on the impact. It isn't a legal requirement anywhere, but it's a real difference in what happens during the kind of fall that causes the most serious injuries.

See the full guide to MIPS helmet technology for a closer look at how the layer works and the testing behind it.

Match the helmet type to how you ride, measure properly rather than guessing, and check the fit in person before deciding. MIPS and the smaller features are worth adding once those first three are settled, not before.

After any significant impact, or every five years regardless of visible damage, since the protective materials degrade over time even without a mark showing.

It depends on the country and resort. Some places, such as Austria, require helmets for children and teenagers by law. Elsewhere it's not a legal requirement but is strongly recommended for every age.

It should feel snug without pressure points, stay in place rather than shifting when you shake your head, and the chin strap should sit secure but still comfortable with room for a finger or two underneath

Wipe the outer shell with lukewarm water and mild soap. Removable padding usually washes at 30°C following the label, and everything should air dry at room temperature rather than on a radiator.

MIPS is a low friction layer that lets the helmet rotate slightly on an angled impact, reducing the rotational force that reaches the brain. It isn't mandatory, but it's a genuine safety benefit worth having.
