Thank you for viewing. This is the Mammut Aenergy TR pants. Size: XL, 52 Purchased in December 2024 at the Mammut Kyoto store and worn 3-4 times. It fit perfectly for someone 175cm tall and weighing 70kg. The pants are stretchy and very comfortable to wear. The original tags from when purchased are still attached. They are in beautiful condition with no stains. This product is only available at authorized retailers and sells out quickly, making it quite rare. Thank you.
