Short answer: the best ski helmet is one that fits your head snugly without pressure points, is certified for snow sports, and works with your goggles. Measure your head, try the helmet on with goggles, and consider a model with a rotational-impact system such as MIPS.
Why wear a helmet
Helmets are standard on the mountain for skiers and snowboarders of every level. They protect against falls, trees, and collisions, and they keep your head warm. Most rental shops include them or rent them cheaply.
Step 1: Measure your head
Wrap a soft tape measure around your head about an inch above your eyebrows and ears, at the widest point. Use that measurement with the brand's size chart; sizes vary between brands.
Step 2: Check the fit
- Snug, no pressure points: the helmet should feel firm all around without painful spots.
- The shake test: with the strap undone, shake your head gently. The helmet should move with your head, not slide around.
- Position: it should sit level, with the front about one finger-width above your eyebrows.
- Chin strap: snug, with room for about one finger underneath.
- Adjustment dial: many helmets have a rear dial to fine-tune fit, which helps if you wear a thin hat or balaclava.
Step 3: Safety features
Certification
Look for a snow sports certification such as ASTM F2040 (common in North America) or EN 1077 (common in Europe). Bike helmets aren't designed for skiing.
Rotational impact protection
Many helmets now include a system designed to reduce rotational forces in angled impacts. MIPS is the best-known version, and other brands use their own systems. See MIPS ski helmets.
Construction
- In-mold helmets fuse a thin outer shell to the foam, which keeps them light.
- Hard-shell (ABS) helmets have a thicker outer shell and are often more durable for everyday knocks.
- Some helmets combine both approaches.
Comfort features
- Adjustable vents let you cool off on spring days and close up in storms.
- Goggle compatibility: no gap between helmet and goggles, and a rear goggle clip to hold the strap. See the ski goggle guide.
- Removable ear pads for warm days, and some models accept audio inserts.
- Visor helmets have a built-in shield instead of separate goggles, which some people with glasses prefer.
Kids' helmets
Buy for the current head size, not one to grow into. A loose helmet doesn't protect well. Check fit each season. See kids ski helmets.
When to replace a helmet
- After any significant impact, even if you can't see damage. Foam can be compressed inside.
- If the shell is cracked, the foam is dented, or the straps are worn.
- Many manufacturers suggest replacing helmets every few years due to wear; check your helmet's guidance.
If you're only skiing a few days, renting is fine. See rent or buy ski gear and the ski trip packing list.
FAQ
How should a ski helmet fit?
Snug with no pressure points, sitting level about one finger-width above your eyebrows, and moving with your head when you shake it gently.
Is a MIPS helmet worth it for skiing?
Rotational-impact systems like MIPS are designed to reduce rotational forces in angled impacts. Many skiers consider them worth it, and they're widely available.
Can I use a bike helmet for skiing?
No. Ski helmets are certified for snow sports impacts and cold conditions, and bike helmets are not designed for skiing.
When should I replace my ski helmet?
After any significant impact, if it's visibly damaged, or according to the manufacturer's replacement guidance.
