Unpredictable weather calls for performance-minded outerwear like and wander’s Pertex Wind Jacket. As the name implies, the style is made using a Pertex fabric called Quantum Air, which is woven using 20 denier high strength nylon yarn with high density. Windproof and water-repellent, the jacket excels in shielding you from the elements. A cinched hood and elasticated cuffs offer added protection, while reflector prints and stitches enhance nighttime visibility. The compact design conveniently stores into an attached pouch for easy transportation when not in use.
