Why We Like The Mammut Haute Route Helmet

Mammut's Haute Route Helmet can do it all. Whether we're chasing backcountry powder, scaling rockfaces, or pedaling on tarmac, this helmet is certified to boost our safety. No matter how we're getting our adrenaline fix, the internal air channels are keeping us chill, while the elastic straps offer to secure our goggles or headlamp. On long approaches to alpine routes, we appreciate the hybrid construction keeping the weight low without sacrificing durability. And on cold midwinter resort days, we're thankful for the included beanie that slips comfortably inside and the large front vents that keep our goggles from fogging up.

Massive sizing - like the overall shape

Circumference is 59cm so I went with L because I know mammut's sizing is a bit small for its stated size usually...This helmet is HUGE. Sizing seems a bit off from the rest of Mammut's line. Word to the wise, try on before you buy...

I’m sure it’s a great helmet…

I already own a Mammut climbing helmet that fits somewhat large. I’m a 58 cm head circumference and already own the medium version of the Mammut climbing helmet. Thinking the sizing should be spot on I ordered the 55-59 cm size of this helmet. I couldn’t even get it on my head all the way. I don’t understand why the sizing would be so off.
