This is a climbing technology mountaineering helmet. I purchased it new in November 2020 from an outdoor specialty website. I took it on three mountain climbs between then and 2023, but it was mostly just carried, with actual use time totaling less than 4 hours. Last year (2024), I applied a Red Bull logo waterproof sticker to avoid confusion with other climbers, and I haven't used it since. It has been unused and stored at home for about a year. Regarding features and condition: There are a few minor, inconspicuous scratches on the surface, but overall, it's been well-maintained and is in good condition. It also has many ventilation holes, making it perfect for the coming season. It's lightweight, and the dial adjustment allows for a good fit. If you're looking for one, how about this? ⚠ Although it's a very beautiful item, it has been purchased and used by someone else, so I would appreciate it if those who understand USED items would consider purchasing it. ※ There are no smokers in my household, and we do not have any pets. - Brand: climbing technology - Model Name: ORION 6X942-1 - Size: 57-62 cm - Weight: 230 g - Color: Light Gray - Features: With ventilation holes, dial size adjustment
