{"type":"firestarter.listing","listing":{"id":"lst_8rtRhsDL","product_name":"Black Arm Warmers","category":"Warmers","description":"Overview:\nFinally - arm wamers with no labels. And they’re good ones, too. Thermal compression fabric with a brushed fleecy inside. We use a custom silicone gripper at the bicep (yes, that’s labeled but no one will see). These are guaranteed to match any and all kits. \nFit:\nThe circumference of our arm warmers is designed to match up with the openings of our jersey sleeves. We'd recommend ordering the same size as your jersey. Ladies should order one size down.\nLengths:\n2XL: 20\"   XL: 19 3/8\"    L: 18 1/2\"    M: 17 7/8\"    S: 17\"   \n ","images":["https://cdn.shopify.com/s/files/1/0486/8548/2147/products/20200921_TheBlackBibs_070.jpg?v=1737750546","https://cdn.shopify.com/s/files/1/0486/8548/2147/products/armwarmer1N.jpg?v=1737750546","https://cdn.shopify.com/s/files/1/0486/8548/2147/products/armwarmer2.jpg?v=1737750547"],"price":20,"currency":"USD","in_stock":true,"inventory_qty":49995,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:42.321Z"},"share_url":"https://firestarter.network/l/lst_8rtRhsDL","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
