Grivel Helmet Technologies

PERFORMANCE HELMETS:

EPP

These helmets are made by a thick EPP (Expanded Polypropylene) shell which both absorbs the shock and protects against penetration. They are very lightweight, but less robust and durable than other types.

SOFT SHELL

Soft Shell (in-mould) helmets are made by a inner EPS (Expanded Polystyrene) core, which absorbs the shock, with a co-moulded thin outer Polycarbonate layer which protects against penetration. These helmets are normally lightweight, but less durable than traditional helmets.

Grivel helmets with Soft Shell construction: Stealth, Stealth Recco

TRADITIONAL HELMETS:

HARD SHELL

Hard Shell helmets are made by an outer thicker ABS shell, which protects against penetration, and an inner EPS (Expanded Polystyrene) core, which absorbs the shock. The EPS is only on the top part, and this is enough to meet the requirements of the norm which covers climbing helmets (CE EN 12492). They are strong and durable.

All-ROUND HARD SHELL

These helmets are made by an outer thicker ABS shell, which protects against penetration, and an inner EPS (Expanded Polystyrene) core, which absorbs the shock. The EPS covers the whole inside part of the shell, on the top and sides. This construction beats the requirements of the norm which covers climbing helmets (CE EN 12492). They are strong and durable, and more safe because they also protect from side impacts.
