FeaturesFeaturesBike Cert (EN 1078)The EN certification for helmets used for bicycling and skating. The major difference in testing 1078 involves needs for more head coverage and for the helmet to pass a deflection or 'roll-off' test of the impact force. BrimHaving a brim on a helmet may be inconsequential to some climbers but they make a great additional bit of protection against sun, rain and falling debris like small rocks or verglass. Multiple SizesThis is helpful for those with particularly small or large heads because helmets that come in 2 or 3 sizes cover a broader range of head size. Usually these are denoted as size 1 or 2, though some brands have S/M and M/L. Face Shield CompatibleFace shields are a part of PPE that could be handy when drilling, developing and cleaning particularly dirty remote routes. Usually only used by work at height professionals. MIPS technologyMIPS or Multidirectional Impact Protection System is a technology designed to reduce the amount of impact force that makes it to the brain. This is accomplished by adding a low friction cap between the liner and the helmet, allowing the shell to deflect around the head rather than transfer the forces from impact directly to the wearer. Many bicycle helmets include this feature and it is starting to be applied to sports like skiing, motorcycling and climbing. Many MIPS helmets are also EN1078 compliant. Ponytail CutoutSo far these are only found in "women's" helmets. It's a cutout / notch area that accommodates a low hanging ponytail hairstyle. RECCO® reflectorThese are used in locating someone missing or buried in an avalanche and are becoming more common in climbing gear due to the increased popularity of ski mountaineering. Though they are more often sold as something to add onto the helmet than being built into one, some manufacturers have begun to build them in. Ski Cert (EN 1077)The EN certification for helmets used for climbing and skiing. This test is simpler than the EN/UIAA one performed for helmets in general, but increases the amount of force that a helmet must endure. Likely this to simulate the faster speeds involved with downhill skiing impacts versus rockfall or climber accidents. This cert becoming more common in helmets as SkiMo popularity increases and more climbers are adding backcountry skiing to their mountaineering repertoire. |

Quick AdjustQuick AdjustQuick Adjust refers to the straps of the helmet. Do you want the ability to ability to "quickly" adjust the fit. This could be a dial, or other plastic pieces. Really, most climbers don't need to change the fit of the helmet often, unless you're climbing with and without hats, or you have big hair that flattens and then requires tightening after climbing for awhile. |
Yes |
VentsVentsRefers to openings in the helmet body to allow air flow. Commonly found in most helmets these days, but often more so in foam and hybrid foam helmets than traditional hardshell polycarbonate shells. Learn MoreClick here to read more on helmet construction |

The Cirrus is built not only for top impact, like most climbing helmets, but also for side and rear impacts as well, making the Cirrus a viable option for ski-mountaineering (there is currently no rating system for ski-mountaineering helmets). Expedition mountaineers, riggers, and other users will appreciate the toughness of the Cirrus as well. When traveling for expeditions, I have often carried my lightweight helmets in my carry-on for fear of them getting crushed in the underbelly of the plane. No problem with the Cirrus. You can rest assured that your Cirrus will survive the three-day transport via mule to the Aconcagua basecamp.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
