Adding accessories

VERTEX and ALVEO helmets adapt to your lighting needs and additional protection requirements in seconds. For self-protection: the user can install a protective VIZIR, VIZIR SHADOW or VIZEN eye shield using the two side inserts, and can add hearing protection with the two side slots. For lighting: each helmet has a front and rear mounting slot for attachment of a PIXA or ULTRA VARIO headlamp, and four positioning hooks for mounting a headlamp with an elastic headband.

Standard customization

Each user can adapt his/her VERTEX or ALVEO helmet according to the need:

  • sheet of transparent stickers: allows the user to display a personal marking on the helmet
  • page of reflective stickers: provides better visibility in the dark
  • absorbent foam: textile foam ensures better absorption of perspiration, needs regular maintenance
  • replacement foams: foams similar to those provided with each helmet. They do not absorb perspiration

(B) Ventilation

(C) Protection against electrical hazards

(D) Reduced risk of choking in case of helmet snagging

(E) Reduced risk of the helmet coming off in a fall
