{"type":"firestarter.listing","listing":{"id":"lst_FtqWqBXp","product_name":"Westcott Polo Shirt Coburn Navy","category":"Jersey-Summer 26","description":"In recent years, the humble polo shirt from tennis origins has undergone something of a makeover, repositioning itself as a much more elevated garment than mere sporting attire. Our Westcott Polo is a case in point - beautifully crafted from 100% organic cotton jersey and featuring a relaxed resort collar, this deep navy style is a great addition to your summer tailored looks, but can equally be worn as part of a laid-back vacation wardrobe.","images":["https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01NAVFRONT.jpg?v=1777882157","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01NAV0109_2.jpg?v=1776250295","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01NAV0113_2.jpg?v=1776250295","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01NAV0115.jpg?v=1776250295","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01NAV0109.jpg?v=1776250295","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01NAV0113.jpg?v=1776250295","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01NAVDETAIL1.jpg?v=1777882156","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01NAVDETAIL2.jpg?v=1777882156","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/OSMK761-COB01NAVDETAIL3.jpg?v=1777882155"],"price":170,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:28.988Z"},"share_url":"https://firestarter.network/l/lst_FtqWqBXp","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
