These are gaiters from OUTDOOR RESEARCH. The material is waterproof and breathable PERTEX SHIELD and Ventla Dry, with a ripstop structure that is durable, lightweight, and easy to fold and store. They are fully openable with Velcro, so you can put them on and take them off while wearing your shoes. The upper part is secured with a nylon belt and a one-touch buckle for easy adjustment, and the belt will not loosen after adjustment. The lower part is secured with a fiber-reinforced nylon belt triple-stitched to the main fabric, providing a sense of security that, unlike cheaper gaiters, allows you to use them for a while even if the stitching comes undone. The size is women's M, suitable for shoes of 24 cm or more. Upper width (flat): 22 cm Lower width (flat): 23 cm Length: 37 cm
