Have you ever been stuck out in the pouring rain wishing you had a windproof, showerproof, and breathable jacket to keep you dry in more ways than one? A Pertex jacket accomplishes all of the above while fitting within a small backpack if you are hiking, a purse if you are travelling to work, or a small carrying case if you are mountain biking. The fabric is extremely breathable and dries quickly, decreasing sweat while keeping your body warm from the harsh wind. There are many varieties from down to microlight inner shells but each provides the same quality protection. Each Pertex jacket comes with a stylish off-set zipper and fleece lined collar to keep you warm and fashionable at the same time. Weighing in at a tiny 3 oz., it will not be a bother to take with you whenever you need it. Full-zip mesh pockets and taped inside seams ensure that you, your clothing, and your electronic devices stay dry.
