The rain jacket is probably one of the most important companions on trips, mountain tours, city excursions or bike tours. But with the large selection of different models in all price ranges, it is sometimes not so easy to find the perfect jacket. The most important criteria for a rain jacket are that it should be waterproof, windproof, breathable and lightweight. It should also be as small as possible to fit in any backpack or pocket. When choosing a jacket, it is important to distinguish between everyday wear and sporting activities.
