Our essential 3-layer shell jacket Letto has got an upgrade. Letto is still very lightweight, still very packable and still equipped with the well proven Dermizax® membrane technology, ensuring excellent wind and water protection. The news is sportier lines and a more modern look. Long underarm zip vents and front pockets in mesh ensure optimal breathability and allow you to regulate your body temperature depending on your level of activity. We dare to say that Letto soon will be your favourite jacket for any outdoor activity in demanding weather.
