Fast and light

Mountain running

Designed with the same guiding principles of alpinism that we apply to all our products, our mountain running collection combines efficiency, performance and low weight for fast moving mountain days.



GORE-TEX Active garments are designed for fast-paced, high-aerobic, done-in-a-day activities even in bad weather. They’re windproof, extremely breathable, can easily be packed away, and have excellent next-to-skin comfort.
