Thank you for viewing! This is a black Briefing Polartec Heavy Boa Hat. The size is M. I tried it on once after purchasing it at an authorized store, but it didn't suit me, so I'm selling it. It mainly uses POLARTEC's best-selling "Polartec Heavy Boa Fleece." This boa material offers exceptional heat retention, breathability, and washability, making it ideal for tough use in golf, outdoor activities, and more. Although I've removed the tag, I will include the original tags that came with the purchase. Shipping will be done with simple packaging, folded. Please feel free to ask any questions or price negotiations♪
