When a garment is advertised as water-proof there are certain requirements that must be met for the company to advertise it as such. Water-proof items can range from a watch, a tent , to a jacket. Each one of these items is tested to determine its' water-proof abilities. For electronics the test is called the Ingress Scale, abbreviation I.P., the rating starts at 1 and goes to 8. If a watch has the rating IPX1, you can safely say this watch is really water-resistant. When you talk about tents or clothes, waterproofing is measured on a scale called the Hydrostatic Head. If you take a piece of the material, and put a tube on top of it, the hydrostatic head rating is how much water you can fill in this tube before the pressure and weight of the water pushes through the material. Proper ‘waterproof’ levels are considered to be 1000mm (25.4 inches) of water, but most decent tents have an HH rating of over 2000mm, and a good waterproof jacket will be around 3000mm+. Outback Trading rain wear is all rated 5000mm, we are proud to boast that we are much higher than many and most companies. With a rating of 5000mm it can be said that even thru the harshest that Mother Nature can dish out Outback Trading can take it!!!
