This wind jacket from adidas Terrex is both light and straight. It’s so lightweight and packable that there’s really no point leaving it at home. The design is fully windproof and lightly water-repellent for both long and short runs. Whether you start running in it or pack it down to use later, it can be easily packed together in its own storage pocket to carry with you in your trail vest or waist bag. The specially woven material provides better breathability where it’s most needed, while providing enough cover to allow you to stay out longer in cold and windy weather.
