| There are several levels of fabric waterproofing, expressed as a column of water in mm (Schmerber or ISO811 Norm). These values are determined in tests during which fabric is subject to increasing water pressure until the water breaks through the fabric. The higher the value in mm, the better the fabric's waterproof quality. Jackets are assembled with sealed seams using strips. The finished product is then tested in a shower, on a mannequin fitted with moisture sensors, which indicate when water seeps in. Very often, jackets are treated with a water repellent siliconebased spray on the outside of the fabric, which means water forms droplets on the surface and slides off without seeping through. This treatment is important. It can be revived by heating the fabric (in a tumble dryer, for instance). | For more comfort, choose a breathable layer |
At sea, it is important to be seen from a distance. This is why jackets have reflective elements such as seam piping or patches, which are highly visible. | To limit water infiltration, tightening systems are often included at the cuffs, neck and waist, etc. Some garments have fleece lined collars and pockets to keep heat in at the body’s extremities. |
