WATERPROOF AND BREATHABILITY NUMBERS

WATERPROOF LEVEL

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.

BREATHABILITY LEVEL

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.
