Many waterproof jackets are designed with a particular activity in mind.
Some are made for high-intensity activities like running or cycling. These make breathability their main feature; helping to keep you comfortable by allowing all the extra heat to escape.
Others balance durability, waterproofness and breathability, and are for sports such as mountaineering or ski touring. These use hardwearing waterproof fabrics that may feel stiffer on the body but can stand up to the demands of the mountains, such as abrasive rocks or carrying a heavy rucksack.
Most people, however, are usually looking for a jacket that provides everyday protection and sits between these two extremes. The selection of these jackets is much wider, covering a range of brands, prices, fits and colours, with some lighter in weight and others stronger depending on your preference.
