The Pertex® Quantum Air Pants are a lightweight windproof shell, a lightweight material developed using Japanese textile technology. The ripstop construction, woven from 20D yarn, holds up well against tears and everyday wear.

An acrylic coating gives them strong wind resistance, while ventilation at the waist and behind the knees keeps the interior breathable. That lightness carries through to the small components and details too, and there are four pockets (two at the sides and two at the back) for practical storage. The waist has an easy-adjust drawcord, and the hem has its own drawcord so you can shape the silhouette to suit.
