Featuring classic Ebbets details such as our signature green underbrim and satin binding, this hat is an easy-wearing wardrobe staple.\n ","images":["https://cdn.shopify.com/s/files/1/1487/1618/files/JackieMontrealCottonTwillBallcap.jpg?v=1744041002","https://cdn.shopify.com/s/files/1/1487/1618/files/JackieMontrealCottonTwillBallcap2.jpg?v=1750959030","https://cdn.shopify.com/s/files/1/1487/1618/files/JackieMontrealCottonTwillBallcap3.jpg?v=1750959030","https://cdn.shopify.com/s/files/1/1487/1618/files/JackieMontrealCottonTwillBallcapdetail1.jpg?v=1750959030","https://cdn.shopify.com/s/files/1/1487/1618/files/JackieMontrealCottonTwillBallcapdetail2.jpg?v=1750959030"],"price":41,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:39.447Z"},"share_url":"https://firestarter.network/l/lst_6qFvQRvo","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
