Many waterproof jackets are designed with an activity in mind.
Some are made for high paced activities like running or cycling. These make breathability their main feature; helping to keep you comfortable by allowing all the extra heat and sweat vapour 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.
The majority of people however need a jacket that provides everyday protection and sits between these two extremes. The good news is that this selection of jackets is very wide, allowing you to choose from a large range of colours, brands, prices and fits.
You may be drawn to a jacket that is particularly light or you may prefer something that feels strong, but as long as your needs are not overly specialised, you are free to choose the one that you like the most.
