The STRATO helmet is very lightweight and comfortable, thanks to its CENTERFIT and FLIP&FIT systems, which guarantee that the helmet fits securely on the head. The adjustable-strength chinstrap makes it ideal for both work at height and on the ground. The unventilated outer shell protects against electrical hazards, molten metal splash and flames. The high visibility version features a fluorescent outer shell with phosphorescent clips and reflective bands, for optimal visibility of the worker, day or night. .
