The North RU8800 Series half mask was designed specifically to accommodate hard-to-fit users. It includes three unique features that make it adaptable to almost any facial structure. The wraparound profile forms to the user's face while the facepiece pleats guide the mask towards the face and the triple flange: which includes three distinct sealing surfaces: provides sealing security for greater freedom of movement. These features work together to allow for the mask to fit a wide variety of sizes - ranging from extra small to extra-large.
- Triple flange provides three sealing surfaces to ensure sealing security
- Soft and flexible silicone facepiece - comfortable for all day use
- Pleats on the facepiece provide gentle pressure to create a better seal
- Wraparound design contours to the user's face
- Low placement of inhalation valves maximizes field of vision
- Exhalation valve provides quick exhaust of warm: exhaled air
- Headstrap assembly includes extra wide cradle suspension and evenly distributes weight
- Woven straps that are easy to adjust and secure
- Fits broad/long facial profiles
