In summary, the two common head injuries when rock climbing are rock falling and impact. The former is the damage caused by falling objects, and the latter occurs more frequently when falling. Head impact may cause concussion and even death. So how does the rock climbing helmet protect the head?
1. Prevent falling objects
There are many things that may fall during rock climbing, such as falling rocks, falling ice, falling equipment. This is why people who climb mountains wear helmets.
You must wear a rock climbing helmet if the climbing route is new, the rock quality is unstable, or there are people moving above. There may be rocks falling off on the steep rock walls of the route, and the accompanying security personnel need to wear helmets more than pioneers, otherwise the rock wedges falling from high altitudes may endanger life.
2. Prevent slipping and hitting
When climbing, the head hitting something is usually when a fall occurs and the climber or the accompanying security personnel may be impacted. If the single rope line is relatively steep and there are convex rocks, a rock climbing helmet is necessary. As for the multi-segment route, climbers will wear a helmet.
After learning the importance of climbing helmets, let's find out the classification of climbing helmets.
According to the different materials used, climbing helmets can be divided into three types:
1. Foam: It is generally made of a kind of foam called EPS, which is flexible. It can absorb energy when subjected to impact and protect the head. This rock climbing helmet has become popular in recent years and is part of the lightweight design in the field of equipment.
2. Hard plastic shell: The outer layer is hard plastic, and the inside is a mesh buffer system, which is heavier than a foam helmet, but also stronger.
3. Hybrid type: The outer layer is a thick piece of plastic, which generally uses ABS material, with a layer of foam as a cushioning system underneath, more durable than foam helmets and lighter than plastic helmets.
