[Material] Wool: 70% Nylon: 30% [Color] Charcoal [Size] FREE [Size Spec] -F- Inner Circumference: 53cm - 63cm Purchased in the November 2024 restock. Used about twice, but I'm selling it because I don't use it. I will be on a business trip overseas until July 4th, so shipping may be delayed until after that date. Thank you for your understanding.
