MAMMUT ROCKRIDER helmet, lightweight and breathable design. - Brand: MAMMUT - Color: Blue - Model Name: ROCKRIDER - Retail Price: ¥9500 Thank you for viewing. I purchased this new and took it on a mountain climb once, but didn't use it. There are minor scratches from when I took it with me, and areas where the gloss has worn off, as shown in the red circle in photo 5. Please understand that this is a used item before purchasing.
