  "question": "Which hats have no plastic in the brim, the sweatband, the closure or the stitching?",
  "status": "nothing-qualifies",
  "updated": "2026-11-11",
  "editor": "cody-wauters",
  "page": "https://amaterio.com/plastic-free/hats/",
  "summary": "Nothing in hats is listed yet. The closest is Amundsen's Classic Hat, a merino beanie whose maker names wool and nothing else for the knit. That's the part you see, and it's fine. The seams and the label inside sit against your head, though, and Amundsen doesn't say what they're made of; sewing thread is polyester far more often than not.\n\nA hat has more places to hide plastic than most people expect, so a hat page that says 100% cotton or 100% wool is a start, not an answer. Check the brim, the sweatband, the closure and the thread before you trust it.",
  "whyPlastic": "The crown is the honest part: cotton twill, canvas, wool, hemp or wool felt. What sits inside it is not. A cap brim holds its shape on a board of polypropylene or polyethylene. Sweatbands are polyester or cotton. Snapback and adjustable closures are molded nylon or polypropylene, and the plastic-free swap is a metal slide or a leather strap. Embroidery and sewing thread are polyester. Beanies are the other trap: most are acrylic, and the ribbing carries elastane. Waxed canvas hats are fine when the wax is named.",
  "whatToCheck": [
    "Fabric: wool, cotton, hemp or linen, or acrylic and polyester?",
    "Brim: stitched wool felt or leather, or a plastic board?",
    "Sweatband and lining: cotton, leather or none, or polyester?",
    "Closure: metal slide, buckle or leather strap, or a plastic snap?",
    "Thread and embroidery: cotton, or polyester?",
    "Beanies: is the ribbing free of elastane?",
    "Waxed fabric: is the wax named?"
