North 7700 Series is the most comfortable and durable half mask available. Its
soft non-allergenic silicone seal provides excellent protection, comfort and
fit. The half mask cradle suspension system allows the face piece to seal evenly
on the face without creating pressure points. Its low profile gives workers a
wide field of vision and does not interfere with protective eye wear. The low
inhalation and exhalation resistance of the 7700 Series makes breathing easier
to reduce worker fatigue.
