    Ascender Mips Helmet

    Sweet Protection's lightest, most packable helmet to date, the Ascender MIPS Helmet is specifically designed for ski mountaineering—with plenty of features for the climb and the descent. This low-profile helmet doesn't sacrifice performance for weight. Instead it uses Advanced Hybrid Variable Elasticity shell technology to transfer the impact in critical zones, while dual-density EPS foam optimizes impact performance specifically for the area and MIPS technology reduces the rotational force transferred to your head in a crash. The Ascender is triple-certified and weighs in at under a pound.

    Great, in theory

    Familiarity:I returned this product before using it

    I wanted to love this helmet, I really did... but I just couldn't. The helmet was too uncomfortable to wear, and I didn't even have it on longer than 5 minutes at a time. First off, the helmet comes with this strange piece of plastic that the inner foam insert attaches to, and the inner piece of plastic is held on by four little rubber pieces. Without swapping out the default foam insert with the included thicker foam insert, I couldn't even stand to wear the helmet due to those little rubber pieces "stabbing" my head. This got better with swapping out the foam insert with the included thicker insert. That said, I took the plastic piece off to check it out and it was damn near impossible to get back in. If one of those thin, flimsy rubber pieces broke while I was on a serious mountaineering quest, the helmet would become loosing/annoying and it would be impossible to clip that back on in the field. In addition to the strange little rubber pieces that hold the inner plastic liner, the adjustment piece at the bottom back helmet to loosen/tighten the helmet was terribly uncomfortable when looking up while the helmet was nice and snugged down. And you know what you do when you're skiing in the backcountry and/or climbing a mountain? You look up, a lot!! The helmet looks cool, and is decently light I guess, but I wouldn't recommend this product at all to anyone that would ever plan on using it without some kind of head buff/beanie etc. I think the Salomon S lab MTN helmet is a better choice - 2 oz lighter, more comfortable, even looks better, and it's cheaper.

    Thanks for the great review Ross!


    Another question, in the pictures shown above for this helmet, it shows two different kinds of occipital straps (the one that rests on the back of the head.) One is fabric, the other seems to be some sort of twist-tighten device. Which one does it actually come with?


    I am not familiar with all the certification codes listed for this helmet. Could this helmet be used for rock climbing as well? I assume so, but maybe not? Anyone know more?

    Hey Kayd! Great question. It's confusing business. The CE EN 1077 Class B means that it meets the required standard for ski/snowboard helmets. Class A helmets offer more protection of the neck and ears. Class B has less surface area protection. Since this helmet does not cover your neck or ears it is Class B. EN is the European standard. The ASTM is the American standard for the same non-motorized snow-sports test. EN 12492 is the European standard for mountaineering/impact protection. This specific certification means that it does protect against blunt impact and would be fine for use in mountaineering/climbing. This article does a great job describing the test methods and is a very quick read: https://www.climbing.com/gear/about-uiaa-and-ce-helmet-certification/
