Our Flight pants offer more warmth and added weather protection to keep you in comfort mode when the mercury drops and the weather conditions become more challenging. Winter protection for your lower body doesn’t have to take up more space in your pack than a water bottle. The Flight pants are stuffed plump with 850 fill power goose down and weigh just 12.5oz (360 grams) per pair, yet they can pack down quite small because the insulation is so compressible. For added protection against moisture and abrasion, these pants feature Gore Windstopper laminated outer shell fabric on the seat and knees. Microfiber outer shell fabric is utilized for the rest of the garment for increased breathability and reduced weight. Features include an adjustable waist belt, adjustable ankle closure with draft protection and dual full length, two-way separating YKK coil side zippers with locking sliders.
