Construction and MaterialsThe poles are made of durable and lightweight 7075 aluminum, which provides high resistance to overload and mechanical damage. This construction makes them more impact-resistant than carbon models, which is especially useful in difficult, rocky terrain. The three-piece construction allows the poles to be folded to a length of approximately 62-65 cm, making them easy to transport and store in a backpack. When unfolded, they offer length adjustment from 100 to 140 cm, making them easy to adjust to the user's height and current trail conditions. One of the main advantages of this model is the 100% natural cork grips, which fit perfectly in the hand and provide exceptional comfort. Cork is a breathable material that absorbs moisture while keeping your hands warm on colder days, making it an ideal choice for multi-season hikes. Additionally, a soft EVA foam extension below the main grip allows for grip changes without the need to adjust the pole length – useful on steep climbs or when overcoming terrain obstacles. Black Diamond Trail Cork poles feature the proven FlickLock® locking system, which allows for quick and secure pole length adjustments. The lock operates via an external lever – requiring minimal force and is comfortable even when wearing gloves. This system is renowned for its high reliability and ease of maintenance.     Technical SpecificationsUsable length: 100 to 140 cm Folded length: approx. 62–65 cm Pair weight: approx. 494 g Material: 7075 aluminum Grips: natural cork EVA foam extension Locking system: FlickLock® (external lock) Tips: tungsten carbide Baskets included: trekking and winter.
