Petzl Strato Lightweight Safety Helmet – ANSI Z89.1 Type I Class E, Yellow

Overview

The Petzl Strato helmet is engineered to be exceptionally light while delivering solid protection. Leveraging CENTERFIT and FLIP&FIT systems, it sits securely on the head, and the adjustable chinstrap offers two retention modes to suit work at height or ground tasks. With the possibility to add Petzl headlamps, hearing protection, and other accessories, Strato is designed to adapt to professional workflows without adding bulk.

Weighing around 435 g, the Strato pairs a hybrid EPP (expanded polypropylene) and EPS (expanded polystyrene) foam liner with an unvented outer shell. This combination aims to absorb impact while keeping the overall profile slim, so you can move through tasks with less fatigue and more freedom of movement.

Lightweight design and secure fit

The helmet uses Dual Centerfit wheels to help you center it precisely on the head. The headband folds into the shell, enabling compact storage and easier transport between sites. This thoughtful design supports both on-site mobility and safer transitions between work zones.

• ULTRA-LIGHTWEIGHT: 435 g thanks to a hybrid foam liner that cushions impact without adding bulk.
• COMFORT AT WORK: a streamlined profile reduces fatigue during extended wear.

Safety features and environmental resilience

The unventilated outer shell is built to meet ANSI Z89.1 Type I Class E standards, providing protection in contexts with electrical hazards, molten splash, and flames. While maintaining a slim silhouette, the helmet remains a practical option for coordinated work attire and protective gear ensembles.

• ELECTRICAL PROTECTION: unvented shell aligns with Type I Class E requirements.
• RESILIENT DESIGN: the shell construction contributes to reliable performance in demanding environments.

Modularity and accessory ecosystem

Strato is designed to work with Petzl accessories, expanding its usefulness across different tasks. The helmet accepts PIXA/DUO headlamps, VIZIR face shields, and standard hearing protection via side slots, letting you tailor protection and visibility to the job at hand.

• MODULAR ACCESSORIES: compatibility with headlamps, face shields, and hearing protection.
• TAILOR-TOOL: adapt the helmet for varying environments without swapping gear.

Real-world usage visions

Imagine performing rope or height work with a secure, lightweight helmet that stays comfortable as you move. Then transition to ground tasks without removing the core gear, using compatible headlamps or shields as needed. The Strato’s design supports flexible workflows while keeping you protected.
