Both sides of the hood are anti-statically treated to EN 1149-1 standard. The hood features a flange with elasticated face and neck openings for a secure and comfortable fit. It is permeable to both air and water vapour, but still effectively repels water based liquids and aerosols. It also gives excellent protection against a wide range of environmental hazards. This includes dust, fine particles and fibres down to 1 micron in size.
