Breathable, Light, Safe

A great lightweight helmet that stays cool during hot days. The tightening system is easy to use, very precise, and comfortable. After using the helmet twice a week for 3 months, the internal padding has remained pristine and is showing no wear. However, as with any helmet, I recommend taking it off when applying deet bug spray because the finish on the top of my helmet is starting to peel a bit.

Great all round helmet, I absolutely love the tightening mechanism and it's overall comfort. It's very durable but still light enough to strap to my pack for long technical mountains

Too Deep

This helmet is deeper than the wall rider. The shell itself rests on the top of my ears and the adjustment arms didn’t want to stay off the base of my ears. The deep shape also gives it a weird profile on head and felt pretty goofy in it. The brow also would not allow me to wear sunglasses in conjunction with the helmet. On the positive side, it is super comfy other wise and really light considering how much additional shell Mammut added to the foam versus leaving it exposed.

Light and size adjusts well for when I'm just wearing the helmet the crag, or have on hat and hoods while alpine climbing in the winter. I think the best review for a helmet is "I forget that I have it on", which certainly applies here! Highly recommend it!

Light comfortable helmet. The strap adjustments are easy to use with a boa style wheel on the back. provides very good coverage of the head vs some helmets which seem to not cover as much of the back of the skull as low as some would like to depending on head shape.
