The Pertex Quantum Air Pants are a lightweight windproof shell pant crafted from Japanese-made Pertex Quantum Air fabric, a 20-denier ripstop material known for its suppleness, tear resistance, and durability. Acrylic coating provides reliable windproofing, while strategically placed ventilation at the waist and behind the knees keeps airflow circulating during high-output activity. Hardware and trims are kept deliberately minimal to reduce weight, and four pockets — two at the waist and two at the back — offer functional storage without adding bulk.
