DETAILS

Be prepared for unexpected situations with this Full-Head Respirator Mask, combining complete head-and-face coverage, integrated glass viewing lenses and a front-mounted filter connection in one distinctive design. Featuring flexible natural rubber construction and an enclosed hood-style fit, it offers a practical addition to emergency supplies, preparedness equipment and suitable protective setups.

Available in beige and black with optional replaceable filter canisters, this reusable respirator provides a convenient full-head alternative to conventional half-face masks. Its enclosed design, clear round eyepieces and flexible construction make it a practical option for organizing protective equipment and preparing for suitable work or emergency situations.

  • Complete Full-Head Coverage: The enclosed hood-style construction extends over the entire head and face, combining facial coverage and integrated viewing windows in one piece of equipment.
  • Clear Glass Viewing Lenses: Two circular glass eyepieces provide a clear view of your surroundings while keeping the eye area enclosed within the mask.
  • Flexible Natural Rubber Construction: Made from natural rubber, the soft and elastic mask body follows the contours of the head and face, providing a flexible enclosed fit.
  • Replaceable Front-Mounted Filter: The chin-mounted connection accommodates compatible cylindrical filter canisters, allowing the filtration component to be replaced without changing the complete mask.
  • Integrated Hood-Style Design: The full-head construction provides an enclosed rubber hood with integrated viewing lenses and a breathing connection, without requiring a separate adjustable head harness.
  • Optional 0.5m Connecting Hose: A flexible 50cm connecting hose is available separately for compatible filter arrangements, providing additional flexibility when positioning filtration equipment.
  • Reusable Respirator Construction: The durable rubber mask body and replaceable filter system support repeated use with appropriate cleaning, maintenance and compatible filtration components.
  • Compact Round Eyepieces: The two circular viewing windows provide dedicated visibility while maintaining the traditional full-head respirator design.
  • Two Color Options: Choose between beige and black rubber housings to suit your preferred protective equipment setup.
  • Flexible Package Configurations: Available options include beige and black masks with or without filters, a two-piece replacement filter set and a separate connecting hose.

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.

Choosing the Right Adult Footwear Size

  • Between measurements: Choose the larger available size in 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.
