I purchased these pants for mountain hiking, but they no longer fit, so I'm selling them. They have an elastic waistband. These are green casual pants made of a nylon and polyurethane blend. - Brand: LATERRA - Material: 91% nylon, 9% polyurethane - Color: Green - Style: Casual pants. The fabric stretches vertically and horizontally. Waist (laid flat): Approximately 60 cm. Although there is elastic, these pants would likely fit someone with a slimmer build. Thank you for looking.
