We collaborated with our yarn spinners and have constructed a unique double twist yarn which allows us to achieve a weight that is not possible using only single yarns. Once you get into this weight category it's imperative to use a ringspun cotton so that the t-shirt remains supremely comfortable, which is exactly what makes our new Sumo t-shirts the most supple and heaviest on the market. \nStill Made In The USA","images":["https://cdn.shopify.com/s/files/1/0337/0573/files/sumo_tee_black_model-003.jpg?v=1764208063","https://cdn.shopify.com/s/files/1/0337/0573/files/sumo_tee_black_model-012.jpg?v=1764208063","https://cdn.shopify.com/s/files/1/0337/0573/files/sumo_tee_black_model-010.jpg?v=1764208063","https://cdn.shopify.com/s/files/1/0337/0573/files/smuo_tee_black_flat-009.jpg?v=1764208006","https://cdn.shopify.com/s/files/1/0337/0573/files/smuo_tee_black_flat-017.jpg?v=1764208006","https://cdn.shopify.com/s/files/1/0337/0573/files/smuo_tee_black_flat-019.jpg?v=1764208006","https://cdn.shopify.com/s/files/1/0337/0573/files/smuo_tee_black_flat-026.jpg?v=1764208006"],"price":38,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:31.981Z"},"share_url":"https://firestarter.network/l/lst_aqiaWAFG","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
