What to Look For in a Ski Helmet
Certification
The common US standard for snow sports helmets is ASTM F2040, which covers impact absorption, retention strength and coverage. OutdoorGearLab says all of the helmets in its roundup meet it. In Europe the equivalent is CE EN 1077, where Class A is aimed at racing and high speeds and Class B at recreational and freestyle use. Look for the sticker inside the shell and the certification on the maker’s product page.
Rotational impact systems
MIPS is a thin, low-friction layer inside the helmet designed to let it rotate slightly relative to the head on an angled hit. Guides describe a movement of roughly 10 to 15 mm. It adds little thickness, so it should not change the size you buy. Several guides make a useful point: a properly fitting helmet without MIPS is better than a poorly fitting one with it. Other makers use their own rotational systems or crushable liners such as Koroyd, which Powder says is used in the Vantage 2.
Construction
Helmets use in-mold, hybrid or hard-shell designs. Hybrid and tri-shell models, such as the redesigned Vantage 2 that GearJunkie describes, reduce weight while keeping coverage. In-mold models are lighter but can feel less durable. Hard-shell models are cheaper and tougher but heavier, which describes much of the budget range.
Ventilation
Adjustable vents let you open the helmet on a warm spring day and close it on a storm day. The Vantage 2 is praised for its 40 vents and closing system, while the Smith Method Pro is noted for limited airflow when it is warm. Backcountry helmets such as the Smith Summit trade insulation for ventilation because you generate heat climbing.
Goggle compatibility
Bring your goggles when you try helmets on. The top of the goggle frame should meet the front of the helmet with no exposed skin and no large gap. A gap lets cold air reach the forehead and can let snow collect after a fall. OutdoorGearLab flags the OutdoorMaster Kelvin II for below-average goggle compatibility, so check the pairing if you buy on a budget.
Fit and Sizing Guide
- Measure around the widest part of your head, about one inch above your eyebrows, with a soft tape kept level front to back.
- Match the number to the specific brand size chart, because sizes differ between makers.
- Put the helmet on with the strap loose. It should sit level, about a finger-width above the eyebrows, and feel snug all the way around with no pressure points.
- Shake your head. The helmet should move with it rather than slide on top.
- If the fit dial is maxed out in either direction, change size.
- Re-check the fit at the start of every season, because pads pack down over time.
Reviewers note that the POC Obex has a specific fit and may require sizing up for some head shapes, and that the Giro Ratio’s larger shell leaves room for a thin beanie. If you ski with a thick hat, try the helmet with it.
Best Overall: Smith Vantage 2 Mips
Switchback Travel, GearJunkie and Treeline Review all name the Vantage 2 Mips as their best overall pick, and OutdoorGearLab calls it the most comfortable. Powder says it uses full Koroyd honeycomb construction. The maker lists a BOA 360 fit system, removable ear covers and adjustable vents, and OutdoorGearLab counts 40 vents. The trade-off is weight, at about 635 g in a large according to that review, and a premium price. It fits skiers who ski most days and want their helmet to feel like part of their kit.
Best Lighter All-Rounder: Smith Method Pro Mips
OutdoorGearLab names the Method Pro its best overall, with a low weight of around 425 g in large and strong impact scores. It has 6 vents, an adjustable dial and compatibility with audio. Reviewers say it works across many head shapes. Its weakness is limited ventilation, which matters if you ski in spring conditions or tend to run hot.
Best Value and Budget
REI calls the Giro Ledge Mips its top value pick, and Switchback Travel and Treeline Review also name it as the best budget or value helmet. OutdoorGearLab’s value pick is the Giro Ratio Mips, which it says scores close to premium models in impact tests though it looks bulky. GearJunkie points to the standard Smith Method Mips as the clear budget option within Smith’s range, since many other Smith models sit at the top of the market. The OutdoorMaster Kelvin II Mips is the lowest-cost option in the roundup and is praised for warmth, but treat the lower goggle compatibility as a real limit.
In practice, budget helmets give you the certified protection and a rotational system. What you give up is weight, ventilation range, fit refinement and finish.
Best for Impact Test Results: Scott Flow Pro Mips
OutdoorGearLab says the Scott Flow Pro Mips took the top spot in both its fast and slow impact tests, with the Method Pro second. It weighs around 522 g in large with 6 vents and adjustable goggle vents. Some skiers find it top-heavy. These are one outlet’s results rather than a universal ranking, and no ski helmet prevents all injuries, so pair any pick with sensible speed and terrain choices.
Backcountry and Freestyle Picks
- Smith Summit Mips: Switchback Travel’s backcountry pick; 33 vents and low weight, but little insulation and lower impact scores in OutdoorGearLab’s testing.
- POC Obex BC Mips: GearJunkie’s most backcountry-specific choice.
- Giro Trig Mips: Switchback Travel’s pick for freestyle and park skiing.
Pick X If You Want Y
| If you want | Pick | Watch out for |
|---|---|---|
| Comfort all day and strong airflow control | Smith Vantage 2 Mips | Weight and cost |
| Light weight and a clean profile | Smith Method Pro Mips | Few vents |
| Safe protection on a limited budget | Giro Ledge Mips or Giro Ratio Mips | Bulkier shape |
| Best reported impact scores | Scott Flow Pro Mips | Top-heavy feel |
| Skinning and uphill laps | Smith Summit Mips | Cold on the descent |
| A very low price | OutdoorMaster Kelvin II Mips | Goggle gap |
Budget Tiers
Budget: Giro Ledge Mips, Smith Method Mips and OutdoorMaster Kelvin II Mips. Mid-range: Giro Ratio Mips, Smith Descend Mips and the Smith Level or Liberty lines. Premium: Smith Vantage 2 Mips, Smith Method Pro Mips and the POC Obex line. Reviewers say that premium helmets add comfort, venting and fit systems rather than a dramatic jump in certified safety.
Care and Replacement
- Replace a helmet after any significant impact, even if it looks fine, because the foam can compress internally.
- Many makers suggest replacing helmets every three to five years, and sooner if the shell cracks or the straps fray.
- Store it away from heat and avoid stickers or solvents that the maker does not approve.
- Read the manual for how to clean the liner and ear pads.
Frequently Asked Questions
Is MIPS necessary in a ski helmet?
It is not required by the ASTM F2040 standard, but nearly every helmet in the reviewers’ roundups includes it or a similar system. Guides describe it as a low-friction layer that helps reduce rotational forces in an angled impact. A well fitting helmet matters more than the label.
How do I know what size ski helmet to buy?
Measure your head about one inch above the eyebrows and compare it with the brand’s chart. The helmet should be snug, level and sit about a finger-width above the eyebrows. If the dial is at its limit, try the next size.
How long should a ski helmet last?
Many makers suggest replacing it every three to five years. Replace it immediately after a significant impact, even without visible damage, since the liner can be compromised. Inspect the shell, straps and buckles each season.
Can I wear a beanie under a ski helmet?
Thin beanies can work, and some helmets with larger shells, such as the Giro Ratio, leave more room. A thick hat will upset the fit and can reduce protection, so try your helmet with the headwear you plan to use. Many skiers prefer a thin helmet liner or the removable ear pads.
Do I need a different helmet for backcountry skiing?
Not strictly, but backcountry helmets such as the Smith Summit Mips and POC Obex BC Mips are lighter and better ventilated. They give up some insulation and, in the Summit’s case, lower impact scores in OutdoorGearLab’s review. Choose one if your day is mostly uphill.
Are expensive ski helmets safer?
Not necessarily. Reviewers note that Giro’s value models score well in impact tests, and that higher prices mostly buy comfort, venting, fit systems and lower weight. Pick the helmet that fits your head and goggles best and that you will actually wear.
