The 757 half mask, made of silicone, has been designed to provide maximum protection against gases, vapours, and particles such as dust. The filters are secured to the mask with a bayonet system. The headband and neck band are adjustable in length. Offers very little resistance to breathing as it includes two filters.

• Main body of the half mask:  Made of blue natural silicone. The design and the material used allow it to adjust to the face in an airtight manner, preventing air from leaking into the interior through the face/mask. The main body houses the two filter connectors and the exhaling valve.
• Exhaling valves:  The half-mask is fitted with an exhaling valve made up of a valve-holder and a membrane, which makes it easier for exhaled air to escape.
• Fastening harness: It has a comfortable neck strap and head strap that can be easily adjusted to the right length. Includes a quick release for a better fit.
• Filters: The filters are secured to the half-mask with a bayonet system.
