Petzl VERTEX ANSI Helmet with Notch Hookups & SENA Comms

The Petzl VERTEX helmet uses a six-point textile suspension with CENTERFIT and FLIP&FIT systems for a secure fit, and its DUAL chinstrap adjusts strength for work at height (EN 12492) or on the ground (EN 397). The unventilated shell protects against electrical hazards, molten metal splash and flames. It fits 53-63 cm head circumferences, weighs 490 g, and is compliant with ANSI Z89.1 Type I Class E. This kit pairs the helmet with Notch hookups and a SENA communication system, as listed in the product options.
