Crafted from Norrøna's proprietary four-way stretch recycled nylon Flex1 fabric, these pants offer exceptional freedom of movement and a barely-there feel. They boast excellent moisture-wicking properties, a PFAS-free DWR finish for light weather protection, and a durable double-weave construction. The design features a sleek, tapered jogger fit with an elastic waistband and internal drawcord, along with zippered elastic ankle cuffs for adaptability. Practical storage includes zippered hand and rear pockets, plus convenient mesh drop pockets. Reflective branding enhances visibility for low-light activities.
Standout Features:
Lightweight & Quick-drying: The Flex1 fabric is incredibly light and dries rapidly, preventing clinging during activity. Exceptional Mobility: Four-way stretch and pre-shaped knees ensure zero restriction for dynamic movements like climbing or running. Weather Protection: PFAS-free DWR sheds light moisture and blocks mild wind, while the fabric effectively blocks wind for warmth when layered. Practical Storage: Multiple zippered pockets (hand, rear) and mesh drop pockets provide secure and accessible storage for essentials. Versatile Fit: Tapered jogger fit with adjustable ankle cuffs and an elastic waistband allows for layering and accommodates various footwear. Durability: Double-weave construction resists snags and pilling, making them suitable for rugged use. Sustainable: Made from recycled nylon with a sustainable manufacturing approach.
