If you want a jacket to keep you dry when running, this will be a very different jacket to one suitable for backpacking or trekking.
There are three characteristics to consider when choosing a jacket based on its fabric, Waterproof Performance, Breathability and Durability. Lighter weight jackets will be a compromise on durability and heavier jackets are often less breathable. Waterproof performance is obviously critical but the highest rated waterproof jackets may not be necessary for your activity. Breathability often becomes the most important characteristic if the jacket is for Adventure Racing when the user will be running or walking fast uphill.
