White helmet with ventilation holes, Elios model. - Brand: Petzl - Model name: Elios - Color: White - Features: With ventilation holes Size 1: 48-56 cm / 300 g Thank you for viewing. This was used by my mother for mountaineering and climbing. The surface has yellowing and scratches. (Please refer to the first and second photos) The inside is in relatively good condition, and the straps are not deteriorated, so it seems that it can be used safely without any problems.
