The Columbia Saturday Trail Stretch Pant was made for the outdoor-loving woman-it's the ultimate outdoor staple. Crafted of a soft nylon and elastane fabric, these pants remain lightweight, yet durable, no matter the weather or activity. High quality materials and expert craftsmanship are the backbone of Columbia?s women's apparel. The technology featured in these pants are necessary for the outdoors. The exterior layer is made up of Columbia?s signature protection fabrics: a combination of water and stain repellency and UPF 50 to help block and shield from UVA and UVB sun rays. The Columbia Saturday Trail Pant is also durable and comfortable - roll-up legs allow you to go from pants to capris almost instantly; the gusset detail, comfort stretch, and articulated knees provide you with a personalized fit. Columbia offers our women's outdoor pants in multiple staple colors, sizes and inseams. To ensure the size you choose is just right, please refer to our sizing chart. To find your waist measurement, measure around your natural waistline. And for your inseam measurement, measure from the top of the interior leg to the bottom of the ankle.
