Choose a helmet labeled for the intended climbing activity, then adjust the exact model so it sits centered and stable. EN 12492 and UIAA 106 are separate standards; a helmet may carry one or both, so read its label. Inspect and retire it according to the maker's instructions, especially after a major impact.
A climbing helmet should fit the wearer and carry the activity label the exact model was designed for.
Check the fit
Use the size range and adjustment steps from the product manual. Petzl’s helmet adjustment guidance says to check that a helmet sits centered and stable; do not use a model that cannot be adjusted to fit properly.
Read the exact certification
The UIAA lists UIAA 106 for helmets. Its current UIAA 106 version 4 took effect in January 2026. EN 12492 is a separate European standard. A maker may list either or both, so verify the exact helmet’s label and product documentation.
Inspect and retire by the maker’s instructions
Inspect the shell, foam, straps, adjustment system and chin strap as the helmet maker directs. Petzl’s helmet inspection guidance recommends model-specific inspection and retirement; its guidance says a major impact can reduce protection even without visible damage. Check the exact helmet manual for its criteria.
Compare construction in our helmet types guide, then browse ropes and protection.
Common questions
Is UIAA 106 the same as EN 12492?
They are separate standards. The UIAA lists UIAA 106 for helmets, and Petzl identifies EN 12492 or UIAA 106 on climbing helmet documentation.
Does every climbing helmet carry both labels?
No. Read the exact model's label and documentation for the standards it carries.
How should a climbing helmet fit?
Follow the model's adjustment instructions. Petzl says the helmet should be well-seated and centered, with minimal movement front to back and side to side.
When should a climbing helmet be retired?
Follow the maker's inspection and retirement rules. Petzl says to retire its helmet after a major impact, even if damage is not visible.
