Casual pants made of fleece material. - Color: Navy - Material: Fleece - Design: With pockets - Style: Casual - Waist: Elastic waist Thank you for viewing. The color is dark navy. The inside is not fleece; it's a smooth jersey-like material. It's thick and should provide considerable warmth. However, the nap of the fabric is flattened around the seat and knees. I've removed as much lint as possible, but some remains. Please consider this a used item and understand before purchasing.
