{"type":"firestarter.listing","listing":{"id":"lst_y7Tc-anV","product_name":"Stadium Heavyweight T-Shirt","category":"Tees","description":"Description\nOur Stadium Heavyweight T-shirt is produced in a custom-developed heavyweight jersey fabric that is the result of years of development. The knit is made with long staple, ring-spun and combed cotton yarn. This yarn quality provides both incredible softness and great durability. Our heavyweight jersey fabric is nearly double the weight of our regular t-shirt, with a tightly knitted construction for a fit that drapes and a more boxy silhouette. The collar is finished with a double-needle mounted construction, a nod to some of the vintage sportswear tees we have always appreciated.\nDetails\n\n\n100% cotton, 10 oz jersey knitted in Portugal.\n\n\nPre-shrunk.\n\n\nScreen printed.\n\n\nMade in Portugal.\n\n\nCare\nWash on cold and tumble dry on low.","images":["https://cdn.shopify.com/s/files/1/0009/8100/8447/files/Stadium_Heavyweight_T-Shirt_Black_Front.jpg?v=1754436551","https://cdn.shopify.com/s/files/1/0009/8100/8447/files/Stadium_Heavyweight_T-Shirt_Milk_Front.jpg?v=1769121370","https://cdn.shopify.com/s/files/1/0009/8100/8447/files/Stadium_Heavyweight_T-Shirt_Navy_Front.jpg?v=1769121370","https://cdn.shopify.com/s/files/1/0009/8100/8447/files/250808_KNICKERBOCKERFW_LOOK19_2027_421da27a-2ce9-4d04-af40-d4bbae772a44.jpg?v=1769121370","https://cdn.shopify.com/s/files/1/0009/8100/8447/files/Stadium_Heavyweight_T-Shirt_Oat_Grey_Front.jpg?v=1769121370","https://cdn.shopify.com/s/files/1/0009/8100/8447/files/250808_KNICKERBOCKERFW_LOOK10_0914.jpg?v=1769121370","https://cdn.shopify.com/s/files/1/0009/8100/8447/files/250808_KNICKERBOCKERFW_LOOK10_1021.jpg?v=1769121370","https://cdn.shopify.com/s/files/1/0009/8100/8447/files/Stadium_Heavyweight_T-Shirt_Group.jpg?v=1769121370"],"price":85,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:23.662Z"},"share_url":"https://firestarter.network/l/lst_y7Tc-anV","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
