Sitting somewhere between a shirt and a jacket, this hardy overshirt is the kind of workwear that works right round the year. Inspired by vintage mechanic’s jackets, it’s got a classic short, slightly boxy shape, with a reassuringly chunky YKK zip making it feel a bit more substantial than your average shirt. Those nifty hidden pockets on the seams are a nice touch too.","images":["https://cdn.shopify.com/s/files/1/2425/1015/files/SS26031628ZIPSHIRTAPPLECINNAMONTWILL-1_1.jpg?v=1770908554","https://cdn.shopify.com/s/files/1/2425/1015/files/SS26031628ZIPSHIRTAPPLECINNAMONTWILL-5_1.jpg?v=1770908554","https://cdn.shopify.com/s/files/1/2425/1015/files/SS26031628ZIPSHIRTAPPLECINNAMONTWILL-2.jpg?v=1770908530","https://cdn.shopify.com/s/files/1/2425/1015/files/SS26031628ZIPSHIRTAPPLECINNAMONTWILL-3_1.jpg?v=1770908530","https://cdn.shopify.com/s/files/1/2425/1015/files/SS26031628ZIPSHIRTAPPLECINNAMONTWILL-4_1.jpg?v=1770908530"],"price":171,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:34.052Z"},"share_url":"https://firestarter.network/l/lst_MQKDaCj9","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
