The knit is made with long-staple, ring-spun and combed cotton yarn, providing both incredible softness and durability. Nearly double the weight of our regular T-shirt, the tightly knitted construction creates a drape with a more boxy silhouette. The collar is finished with a double-needle mounted construction, a nod to the vintage sportswear tees we’ve always appreciated. \nDetails\n\n100% cotton, 10 oz jersey knitted in Portugal\nPre-shrunk\nScreen-printed\nMade in Portugal\n\nCare\nWash on cold and tumble dry on low.","images":["https://cdn.shopify.com/s/files/1/0009/8100/8447/files/KNY_T-Shirt_Navy_Front.jpg?v=1768254573","https://cdn.shopify.com/s/files/1/0009/8100/8447/files/KNY_T-Shirt_Olive_Front.jpg?v=1768254574"],"price":85,"currency":"USD","in_stock":true,"inventory_qty":69993,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:23.603Z"},"share_url":"https://firestarter.network/l/lst_oh-3bOTM","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
