How it Works
Today most waterproof fabrics have been treated with a laminate or coating of, for example, PU (polyurethane), rubber or PVC (polyvinyl chloride) or wax to make it water repellent, while still allowing water vapour to pass through.
A fabric’s water resistance i.e. the level to which it repels water, “is measured, in mm, which can be suspended above the fabric before water seeps through”, while it’s breathability (or vapour transmission rate) is “measured by the rate at which water vapour passes through, in grams of water vapour per square meter of fabric per 24 hour period (g/m2/d)”. According to GO Outdoors a garment is judged to be 100% waterproof if it meets the British Standard of 3 PSI (Pounds per Square Inch), which can withstand 1500mm of pressure. Today most types of

- Look at the fit – a waterproof item that’s too small will be uncomfortable while one that is too large might let water in
