Helmet
Choose a UIAA/CE certified climbing helmet that fits well. There are two basic types:
Suspension[edit]
A solid outer shell supported by an interior webbing suspension system. Energy is absorbed primarily by elastic deformation; that is, the shell deforms on impact and will normally return to its original shape afterward. This absorbs the energy of a vertical impact, such as a falling rock.
- Advantages: durable, cushions the head well under a waterfall and against minor bumps
- Disadvantages: heavier, some models don’t float
Foam[edit]
A crown of polystyrene or polypropylene foam protected by a thinner shell. Energy is absorbed by plastic deformation; that is, the crown deforms permanently on impact as the foam is crushed. This disperses the energy of a vertical impact and the frontal, side and rearward impacts more common with a fall. Durability varies according to shell thickness, which can range from thin plastic sheeting to a semi-rigid shell.
- Advantages: lightweight, floats
- Disadvantages: less durable (depends on thickness of shell), doesn’t cushion the head as well under a waterfall
