This is an Arc'teryx beanie. I purchased this through a secondary market, but it didn't suit me, so I haven't worn it. The seller claimed to have purchased it from the official store, so I believe it is authentic. Please understand that this is a pre-owned item from a secondary market before purchasing. - Brand: ARC'TERYX - Color: Navy - Material: 49% Cashmere, 49% Wool, 2% Nylon - Design: Graphic Design - Style: Knit Cap Thank you for looking.
