Description
Replacement sweat-absorbing, machine-washable foam liner for older Petzl VERTEX BEST, ALVEO and VERTEX VENT helmets (2014–2019).
Petzl VERTEX Foam – Replacement Liner for Older Helmets
The Petzl VERTEX Foam replacement restores comfort and hygiene inside older Petzl helmets. Designed specifically for VERTEX BEST, VERTEX VENT and ALVEO helmets sold between 2014 and 2019, this foam insert helps keep your headgear comfortable during long workdays. Because foam naturally compresses and absorbs sweat over time, replacing it ensures your helmet feels fresh again.
Refresh Comfort and Extend Helmet Life
This replacement foam absorbs perspiration effectively and helps regulate comfort inside the shell. As the material is machine washable, you can clean it easily and keep your helmet hygienic day after day. Regular washing also supports long-term freshness, which is ideal for anyone working in warm or demanding environments. By replacing worn foam, you maintain a stable and secure fit throughout your tasks.
Simple, Practical and Ready to Fit
The Petzl VERTEX Foam installs quickly without tools, which makes maintenance straightforward. The standard “regular” foam suits most head sizes, while a thicker option supports smaller head sizes where a closer fit is needed. Once fitted, the lightweight polyethylene construction maintains comfort without adding bulk. This practical design helps your helmet perform as intended.
Ideal for Older Petzl Helmet Models
If your VERTEX BEST, ALVEO or VERTEX VENT helmet has seen years of use, this replacement foam helps restore interior quality and user comfort. It is an effective way to prolong the value of older helmets while keeping daily wear safe and pleasant. Keeping a spare foam liner ready makes it even easier to refresh your gear when needed.
