Familiarity: I've put it through the wringer

Took this on an 8 month South American climbing trip. It's light, good looking, comfortable, visor, headlamp compatible, sheds icefall well, etc. Pretty much all I need in a helmet, with the exception of a pretty serious design flaw.

It was strapped to my backpack on a slippery alpine descent, and I fell and it broke along the plastic/EPP foam transition when I slipped. It's a pretty prominent point of weakness that doesn't exist in a side by side comparison with the Petzl Sirocco (and it's a few bucks cheaper). Along each of the three struts on half the helmet!

As a mechanical engineer, I notice that this design could be improved by increasing the bend radii for strain relief, or just increasing the cross sectional area along the fracture line. What a bummer on an otherwise great helmet. Hope it's addressed in future revisions, or my next will be a Sirocco (despite how ugly they are, they've also got a 3 year guarantee that Mammut doesn't have, as well as being a few bucks cheaper)

Whatever, i'm gonna put some GOOP on it and keep the tape fix, as it'll still shed impacts from above. I'm just a little disappointed in the engineering!
