This is a Mammut Skywalker 2 helmet, purchased new in January 2020 and only tried on for confirmation. It has never been used for mountain climbing or outdoor activities. This helmet is ideal for mountaineering and climbing. The dial adjustment allows for easy adjustment while wearing the helmet, providing an excellent fit. It also comes with a dedicated Mammut helmet storage case and original box (⚠ The box has some damage). There are no visible scratches or deterioration on the interior or exterior. The product has been stored carefully in a box in a dark place, so it is in very good condition and almost new, considering its age. However, as it has been tried on and is a pre-owned item, we would appreciate it if you could understand this before making a purchase. ※ There are no smokers in our household, nor do we have any pets. - Model Name: Skywalker 2 - Color: Orange - Size: (Dial adjustment) 53-61cm - Brand: Mammut - Weight: 360g
