DETAILS
Be prepared for unexpected situations with this Full-Face Respirator Mask, designed to combine respiratory and eye coverage in one practical piece of protective equipment. Featuring a wide panoramic visor, replaceable 40mm filter canister and adjustable five-point head harness, it offers a convenient full-face design for suitable protective tasks. Whether you're organizing emergency supplies, preparing for potential disruptions or equipping yourself for demanding work environments, this mask makes a practical addition to your protective equipment.
With an activated carbon filter canister, flexible sealing frame, impact-resistant face shield and adjustable head straps, this reusable respirator combines practical filtration equipment with comfortable full-face coverage. Its replaceable filter system and durable construction make it suitable for ongoing maintenance and preparedness needs.
- Full-Face Respirator Coverage: Combines nose, mouth and eye coverage in one integrated design, providing a complete facial enclosure compared with conventional half-face respirators.
- Wide Panoramic Visor: The large transparent viewing window provides a broad field of vision, allowing you to maintain visibility of your surroundings while wearing the mask.
- Anti-Fog & Scratch-Resistant Face Shield: Features a wide visor with anti-fog and scratch-resistant construction to support clear viewing during suitable work and observation activities.
- Replaceable 40mm Filter Canister: Uses a standard-size 40mm threaded filter connection, allowing the front-mounted canister to be removed and replaced with compatible cartridges.
- Activated Carbon Filtration: The included filter canister combines activated carbon granules and particulate-filter material in a layered filtration design. Filtration performance depends on the cartridge's specific rating and the airborne substances present.
- Five-Point Adjustable Head Harness: Five adjustable attachment points help distribute tension around the head, allowing you to customize the mask's positioning and achieve a secure fit.
- Flexible Double-Sealing Frame: The contoured facepiece features a flexible sealing structure designed to follow facial contours and support a secure fit around the face.
- Built-In Dual-Valve Design: The integrated valve system supports airflow through the respirator during normal breathing.
- Internal Breathing Cup: A separate nose-and-mouth section creates a defined breathing area inside the full-face enclosure, helping separate the breathing space from the main visor.
- Comfortable Contoured Construction: The molded facepiece and adjustable harness provide flexible positioning and comfortable contact around the face during appropriate protective activities.
- Reusable Mask with Replaceable Filters: The durable mask body supports repeated use with compatible replacement cartridges, making filter maintenance convenient without replacing the complete respirator.
- Practical for Work & Preparedness: The full-face format and replaceable filter system make the mask convenient to store with maintenance equipment, workshop supplies and emergency preparedness gear.

Adult Footwear Size Guide
Our adult footwear is listed in US sizing. Sizes are displayed as M for US men and W for US women. When two sizes are shown together, such as M 6 / W 7.5, they refer to the same selectable size.
How to Measure Your Foot
- Use a sheet of paper: Place it on a hard floor with one edge against a wall.
- Stand against the wall: Place your heel lightly against the wall with your full weight on your foot.
- Mark your longest toe: Mark the paper at the tip of your longest toe.
- Measure heel to toe: Measure from the edge of the paper to your mark in inches or centimetres.
- Measure both feet: Use the longer measurement if your feet differ.
- Wear your usual sports socks: Measure with the type of socks you plan to wear with the footwear.
- Measure later in the day: Feet can become slightly fuller throughout the day.
Important: Use your actual heel-to-toe measurement. Do not add extra length before checking the chart.

- Wider feet: If you regularly wear wide-fit footwear and the style has no width option, consider choosing the larger size.
- Performance footwear: Cycling shoes, cleats and other fitted sports footwear may feel snugger than casual shoes.
- Sports socks: Consider the thickness of the socks you plan to wear.
- Sandals: Your heel and toes should sit neatly within the sole without overhanging.
