This is a collaboration muffler purchased at a Helinox limited popup. I think it was around 20,000 yen. It's a beautiful item, only tried on. It's designed to be worn over the shoulders with your hands inside, and it's warm. Length: 170 cm x Width: 18 cm I think it's quite rare. - Brand: Nanga - Model Name: Helinox - Color: Black - Type: Neck Warmer - Design: Down material Thank you for looking.
