These are gaiters from OUTDOOR RESEARCH. The material is PERTEX SHIELD and Ventla Dry, which are waterproof and breathable. They have a ripstop structure, making them durable, lightweight, and easy to store when folded. They are fully openable with Velcro, allowing for easy on and off even with shoes on. The top is secured with a nylon belt and a one-touch buckle for easy adjustment, and the belt will not loosen after adjustment. The bottom is secured with a fiber-reinforced nylon belt, triple-stitched to the main fabric. Unlike cheaper gaiters, even if the stitching comes undone, they can still be used for a while, providing peace of mind. Size is L, suitable for 25.5 cm and above.
