A helmet for snowy and rocky mountains.

Mammut's Alpine Rider Helmet is certified for skiing as well as climbing so you can ride the alpine with the same protection all year long. This in-mold helmet uses Mammut's Micro Shell for lightweight toughness. Removable winter padding keeps you warm in the cold temperatures while fourteen large vents ensure breathable airflow in the warm temps. The thumb wheel adjustment works even with gloves on, and four clips keep headlamps in place.

Darth Helmet

  • Familiarity: I've used it once or twice and have initial impressions

I have a relatively small head (about 57cm), though within the range specified. The helmet felt decently comfortable with the ski padding insert attached. With the ski padding replaced by the thinner climbing padding, I felt like Darth Helmet from Spaceballs, just a tiny person under a gigantic lid. The shape was very round, so even though I dialed it tightly, there was still space side to side. These are obviously personal problems, but if you have a smallish, oval head like me, this is not the helmet for you.

Great lid

    Been looking for a helmet like this for years. Good for both skiing and climbing. Zero complaints. Mammut nailed it with this one. Definitely best of its kind by far

    You can count the number of helmets dual-rated EN 12492 & 1077 on one hand--and some aren't available in the States. So it's a good first try, but I expected more from Mammut and the price-point.

    Same issues with the goggle strap. But most modern goggles have grips on the straps, so wear it like you would on any other ski or snowcross helmet. The headlamp can flip down easily, so you'll want to add the standard velcro tape to the helmet and light (fuzzy piece on the light!)

    Wildland fire supply companies sell add-on goggle and headlamp clips that work WAY better than what Mammut did here. They should have modeled it after these products instead of preferring design over function.

    My helmet rotated back easily and I had to adjust the chin strap so the front was shorter than the rear. When taught the straps are angled about 45 degrees from the default. Not a deal breaker, I've just never needed to adjust a helmet to that degree before.

    Not that most alpinists care terribly about style. But so you know, when you're wearing goggles it feels and looks like a light 3/4 motorcycle helmet. With no goggles you resemble a very lost dirtbag who wandered into a resort by mistake.

    Hmm, i hate to criticize but this just isn't my favorite helmet. I had high hopes because I really like the Mammut Rock Rider Climbing Helmet but this as a ski touring helmet just doesn't really help me out much. I thought this option would help keep goggle straps out of the way like my alpine helmet but still be as light as my climbing helmet and allow me a dedicated ski touring helmet....but in reality it just was kind of a headache trying to keep my ski goggle strap attached. The concept is there, but refinement is needed. For skiing in the PNW I end up wearing my Mammut Rock Rider or Petal Sirocco with a beanie underneath. and goggles under the helmet. That combo seems to work better than fooling around with this option.

    I like the idea of this helmet but it's just a little too finicky for me.

    Goggle Retention is Extremely Fragile

      Like the title says, its pretty much worthless in its current design. Sweet helmet they just need to make it a tad more burly.

      Got the Job Done! A few flaws.

        So far I have used this for a week of backcountry skiing in the Tetons. I wanted a lightweight helmet that would work for both skiing and for climbing. This helmet fits the bill pretty well. I used the climbing inserts in the helmet while skiing and frequently wore a beanie underneath. Overall the helmet was super comfortable and I frequently just left it on while skinning. The headlamp clips are great. The major complaint I have is with the goggle system. The system secures the goggles to the helmet well but you have to be careful between the balance between the helmet sizing and goggle strap tightness. When I wasn't wearing a beanie and used the adjustment to tighten the helmet most of the way, any pressure pulling the helmet forward from the goggle strap would pop the adjustment strap out of the helmet forcing me to remove everything and start again. It was less of a problem with a beanie on and the helmet fit less tight. I managed it by the end of the trip but it was super annoying by then.
