It's hard to have a good head at a chossy crag without a hard helmet protecting your brain box from falling rocks, but it's also annoying to climb with a bulky helmet weighing your head down. Mammut offers a solution with its lightweight Rock Rider Climbing Helmet. The EPS core with Micro Shell exterior is very strong while remaining extremely lightweight. And the in mold interior offers all day comfort whether you're climbing sporty crags or multi pitching up an alpine ascent. Sixteen ventilation openings give this helmet a wide range of uses including ice and mixed climbing, and even ski touring. You can adjust both the headband and the chin strap for an ideal fit no matter the shape of your melon, and both the band and strap can fold into the helmet for a more compact fit into your backpack. Four clips stabilize your headlamp so it doesn't slide up or down your face while you ascend in the early mornings and descend while the sun drops below the horizon.
