{"type":"firestarter.listing","listing":{"id":"lst_oPeb4Lbp","product_name":"Half-Zip Sweatshirt - Faded Navy","category":"Sweatshirts","description":"Through the countless hours we've spent pouring over our archival garments and historical photographs, we found ourselves up to our ears in beautiful vintage half-zip workshirts. Rather than going after a 1-to-1 recreation of those beauties, we decided to put a fun little spin on the half-zip shirt.\nUsing the same cotton fleece from our crewneck sweatshirts, we came up with this variation of a sweatshirt. Designed to be worn as a shirt, sweatshirt/sweater, or something in between, the half-zip sweatshirt is an amazing new standout piece for us. \nTake your normal shirt size for a regular fit. Size up for a looser fit.\n\nHalf zip\nSignature acorn flap breast pockets\nTop button closure\n100% BCIS Certified Cotton\nMade in Portugal\n","images":["https://cdn.shopify.com/s/files/1/0324/6935/2579/files/APC_2560-hdr.jpg?v=1694628203","https://cdn.shopify.com/s/files/1/0324/6935/2579/files/APC_2563-hdr.jpg?v=1694628204"],"price":188,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:11.674Z"},"share_url":"https://firestarter.network/l/lst_oPeb4Lbp","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
