Can a Skiing Helmet Be Used as a Rock Climbing Helmet?

Helmets are used in many outdoor activities to protect against head injuries. Many people do not use helmets, despite the danger that may come from the activity. When using a helmet, it is important to find one that adheres to the safety guidelines of the activity you are participating in. Having a helmet on during rock climbing and skiing activities is important. But the type of helmet you wear does matter. In theory, you could wear a ski helmet while rock climbing, but you may run into some complications.

Helmet Elements

A helmet isn't a "one size fits all" activities piece of equipment. They look very similar on the surface, but the two types of helmets are very different on the inside. Both rock climbing and ski helmets have specific elements designed to protect the wearers from specific dangers of each activity. Rock climbing helmets have suspension or foam interiors that deform upon impact. This feature allows the helmet to absorb the impact of the fall so the climber's head is receives minimal damage. Suspension helmets have a hard outer shell and elastic interior. The elastic system deforms upon impact but returns to the original form afterward. The foam helmet has a thin outer shell and also deforms upon impact. This helmet keeps the deformed shape, however.

Ski helmets do not have such sophisticated systems. They are charged with covering the head with protection from the weather and impact. However, the impact isn't usually with such hard terrain as that the rock climber experiences. Ski helmets have masks to help keep the face protected from wind and snow as well. The interior is cushioned, but they don't have the deformity options that the rock climbing helmets do.

To Answer the Question...

Although there is not law prohibiting you from wearing a ski helmet for rock climbing, it would be unwise to do so. Rock climbers perform in the roughest terrain. Any type of fall would result in the head impacting a very hard object that isn't cushioned by snow. This is why the foam or elastic systems are not only prudent, but also necessary for the activity. The ski helmet would cover the head and provide some cushion, but not nearly enough to protect the head against impact with rock. So, when choosing your helmet, be sure to choose a helmet specifically designed for rock climbing.
