The Portwest P371 is a moulded FFP3 respirator designed to fit most face shapes. Its exhalation valve lowers heat and moisture build-up inside the mask, which helps when you work in hot and humid conditions.
A soft net cover protects the outside of the mask. An all-round foam gasket, moulded nose bridge and wide adjustable head straps help you achieve a secure fit. Each pack contains five masks.
