{"type":"firestarter.listing","listing":{"id":"lst_jXAoFhMz","product_name":"Penryn Overshirt Robbins Multi","category":"Shirts-Winter 25","description":"Brushed cotton shirts really come into their own in winter thanks to that slightly raised nap which gives a soft fuzzy handle. They feel great, but also lend your winter fits some textural depth. Our Penryn style is an overshirt style that can be worn as a regular shirt too. This version features beige multi check for a rugged workwear look.","images":["https://cdn.shopify.com/s/files/1/0272/3338/6538/files/Penryn_Overshirt_Robbins_Multi_Flat_Shot_1.png?v=1763979319","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/Penryn_Overshirt_Robbins_Multi_Model_Shot_3.jpg?v=1773848305","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/Penryn_Overshirt_Robbins_Multi_Model_Back_Shot_2.jpg?v=1773848305","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/Penryn_Overshirt_Robbins_Multi_Model_Shot_2.jpg?v=1773848305","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/Penryn_Overshirt_Robbins_Multi_Flat_Shot_2.jpg?v=1773848305","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/Penryn_Overshirt_Robbins_Multi_Flat_Shot_3.jpg?v=1773848305","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/Penryn_Overshirt_Robbins_Multi_Model_Shot_1.jpg?v=1773848305","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/Penryn_Overshirt_Robbins_Multi_Model_Back_Shot_1.jpg?v=1773848305","https://cdn.shopify.com/s/files/1/0272/3338/6538/files/Penryn_Overshirt_Robbins_Multi_Flat_Shot_5.jpg?v=1763987857"],"price":105,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:29.411Z"},"share_url":"https://firestarter.network/l/lst_jXAoFhMz","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
