I have used it once so far while climbing Royal Arches at Yosemite National Park. Nothing has fallen on my head so far, but the helmet feels very secure and doesn't shift at all once adjusted correctly. The chin strap has a felt sheath that adds to the overall comfort of the helmet. We climbed for about 11 hours that day, and not once did I feel the urge to take it off. I highly recommend it.
