WATERPROOF AND BREATHABILITY NUMBERS WHAT DO THEY REALLY MEAN FOR WORKERS?

MM WATERPROOF

150D 190T

3,000 MM

10,000 MM

20,000 MM +

The minimum rating for a garment to be called waterproof, suitable for working in light to moderate rain.

Will withstand moderate to heavy rain but may soak through if subjected to pressure such as kneeling in very wet conditions.

Suitable for those working outdoors in extreme weather conditions, wind and heavy rain.

Waterproof ratings are measured in millimetres (mm), ranging from 800mm to 20,000mm. For example 10,000mm indicates that a fabric can withstand the pressure of a 10 metre tall column of water pushing on it before it starts to let any water through.

MVP BREATHABILITY

3,000 MVP

20,000 MVP +

10,000-20,000 MVP

Suitable for light physical activity which causes minimal perspiration.

Suitable for heavy physical activity which results in significant perspiration, will require rainwear this breathable.

Suitable for heavy physical activity which results in significant perspiration, will require rainwear this breathable.

MVP is Moisture Vapour Permeability expressed as g/m²/24 hours, it is the number of grams (g) of water vapour that can pass through a square metre (m²) of fabric from the inside to the outside in 24 hours. The larger the number, the more breathable the fabric.
