When you need a helmet that'll protect you, even after a few up-close meetings with Mother Earth, look to the POC Crane Helmet. This Swedish-designed, skate-style lid has a polycarbonate shell with progressively denser EPS foam lining for enhanced impact protection. There are eight vent holes up top, so you won't cook your brains out, either, when you're hiking back up the same section in the summer heat. Out back, there's a sizing-adjustment system to make sure the helmet fits as it should, not like some floppy skate helmets do.
