Developed for fast ascents. This lightweight, wind- and water-resistant jacket made of stretch Dynastretch™ fabric is an impressive stretch woven material optimized with laser perforations for ventilation, plus an athletic fit. In addition, the fabric is abrasion resistant and at the same time very breathable - even during intense physical efforts. Mesh fabric has been integrated at the back for ideal ventilation, especially for increased comfort when carrying a pack. The jacket features two roomy zip pockets, a separate smartphone pocket, and it can also be packed quickly and quite small to stow in a pack.
