{"type":"firestarter.listing","listing":{"id":"lst_MO4ZbL72","product_name":"Cornerstone Jacket","category":null,"description":"Some pieces earn their keep the moment cold weather hits. The Cornerstone Jacket is one of them. We wanted something warm, durable, and easy to wear every single day of the season. A jacket that feels familiar out of the box but only gets better with time. This is the result.\nThe exterior is a tough ripstop shell built to shrug off abrasion and keep you moving without worry. Inside, a soft polar fleece lining adds real warmth and comfort. The insulation is made from a partially plant based polymer that traps heat without adding weight. It is the kind of cold weather layer you throw on for early rides, long drives, or slow mornings around town. Clean lines, western inspired yokes, and workwear details round it all out.\nTHE SPECS + DETAILS\n\nExterior: durable ripstop cotton blend\nInsulation: partially plant based polymer fill\nLining: warm polar fleece body with smooth sleeve lining\nSnap front closure with reinforced placket\nDual snap chest pockets\nHand pockets with soft interior lining\nWestern style yoke stitching\nCuff snaps for adjustability\nStandard fit for easy layering\nImported\n","images":["https://cdn.shopify.com/s/files/1/0767/3853/files/CornerstoneJacket-Green-Front-30.jpg?v=1762471144","https://cdn.shopify.com/s/files/1/0767/3853/files/CornerstoneJacket-Black-Front-34.jpg?v=1762471144","https://cdn.shopify.com/s/files/1/0767/3853/files/CornerstoneJacket-Green-Open-31.jpg?v=1762471144","https://cdn.shopify.com/s/files/1/0767/3853/files/CornerstoneJacket-Green-Back-32.jpg?v=1762471144","https://cdn.shopify.com/s/files/1/0767/3853/files/CornerstoneJacket-FitModel-1.jpg?v=1764962966","https://cdn.shopify.com/s/files/1/0767/3853/files/CornerstoneJacket-FitModel-2.jpg?v=1764962966","https://cdn.shopify.com/s/files/1/0767/3853/files/CornerstoneJacket-Green-Details-60.jpg?v=1764971193","https://cdn.shopify.com/s/files/1/0767/3853/files/CornerstoneJacket-FitModel-7.jpg?v=1764971193","https://cdn.shopify.com/s/files/1/0767/3853/files/CornerstoneJacket-Green-Details-59.jpg?v=1764971193"],"price":89.5,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:29:59.205Z"},"share_url":"https://firestarter.network/l/lst_MO4ZbL72","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
