The best ski helmets for big heads are shells that publish an XL or 2XL size range above 62cm, like the Sweet Protection Trooper 2Vi MIPS and Anon Raider 3, rather than helmets that top out at a generic 'large' and rely on a dial to stretch the fit.

I've got a big head myself, and I know the annoying moment at the shop when the 'large' helmet is clearly the biggest size they carry and it's still snug on you. A lot of helmet lines quietly stop their shell sizing at 59-61cm and just hope the fit dial covers the rest. It usually doesn't. Here's what to actually check before you buy.

What to look for

A published shell size that explicitly reaches XL or 2XL (generally 62cm+) — not just a fit-dial range advertised as 'one size fits most'
Round oval vs. long oval internal shape — big heads aren't just larger, the shape matters, and a helmet built for a narrower oval will pinch the temples even if the circumference matches
In-mold construction in the largest sizes, since some brands switch a big-head shell to a heavier hybrid or hardshell build that adds bulk and weight right when you don't want it
MIPS or an equivalent rotational-impact layer that's actually integrated into the XL shell, not just offered on the smaller sizes
Avoid any helmet that markets itself as 'universal fit' without a published size chart — that's usually a sign it was designed around an average head and won't work well at either end

Best overall for big heads

Sweet Protection Trooper 2Vi MIPS

Sweet Protection runs its shell sizing well past what most competitors offer, and the 2Vi (MIPS) version keeps the rotational protection in the largest sizes instead of dropping it. It runs a bit heavier than ultralight in-mold helmets, so if you want the lightest possible lid this isn't it.

MIPS integrated across the full size range

Best value for big heads

Anon Raider 3 Helmet

Anon's Raider 3 goes up to XL and keeps the same in-mold construction and Boa fit dial across every size, so you're not getting a downgraded build just because you need the bigger shell. It's a straightforward all-mountain helmet without a lot of extra features, which is exactly what some people want.

In-mold shell available up to XL
Boa fit dial for micro-adjustment
Compatible with Anon's goggle/helmet integration

Best for round oval head shapes

Giro Union MIPS Helmet

Giro's Union runs a noticeably rounder internal shape than some of its own lineup, which matters if you've tried an XL helmet before and still felt pressure at the temples. It's a great option if round oval fits you — if you're long oval shaped, it can still feel tight even in the largest size.

Best ventilation — check size chart carefully first

Smith Vantage MIPS

The Vantage is one of the best-ventilated helmets on the market and a longtime favorite of mine for hot spring days, but its largest published size runs smaller than the three above it. Measure your head before buying — it's a great helmet, just not automatically a big-head solution.

MIPS included

Frequently asked questions

What size head is considered 'big' for ski helmets?

Most standard adult helmet lines top out around 59-61cm circumference. If you measure above that — into the low 60s or beyond — you're looking at the XL or 2XL tier, and not every brand offers one.

Do ski helmets come in XL or 2XL sizes?

Yes, but not universally. Brands like Sweet Protection, Anon, and Giro publish XL options on select models, while other popular helmets stop at large and rely on an internal fit dial to cover the gap, which often isn't enough for a genuinely large head.

Is a bigger ski helmet heavier?

Sometimes. A few brands switch their largest shells to a hybrid or hardshell construction instead of full in-mold, which adds weight. Check the construction type at your specific size, not just the model name, since it can differ across the size range.

How do I know if I need a round oval or long oval ski helmet?

Look in a mirror from above at your bare head, or check where a snug baseball cap presses first — if it's your temples, you're likely long oval; if pressure is even all around, you're closer to round oval. Manufacturers list this shape info on their fit guides, and it matters as much as raw size for big heads.

Can I just buy the largest 'universal fit' ski helmet instead?

I'd avoid it. Helmets labeled universal fit without a published size chart are usually built around an average circumference and shape, and they tend to underperform at either end of the sizing spectrum, including for bigger heads.
