That 230gsm cotton fabric is just the right weight for year-round wear, with a reassuring almost-heavyweight feel that gives it a nice dollop of vintage sportswear flavour. Whether you go for short sleeve, long sleeve, patch logo or big ol’ graphic, you’ll have made the right choice.","images":["https://cdn.shopify.com/s/files/1/2425/1015/files/SS26057606HEATWAVETEEISLANDGREEN-1_1.jpg?v=1768473576","https://cdn.shopify.com/s/files/1/2425/1015/files/SS26057606HEATWAVETEEISLANDGREEN-2.jpg?v=1768473576","https://cdn.shopify.com/s/files/1/2425/1015/files/SS26057606HEATWAVETEEISLANDGREEN-3_1.jpg?v=1768473581","https://cdn.shopify.com/s/files/1/2425/1015/files/SS26057606HEATWAVETEEISLANDGREEN-4_1.jpg?v=1768473579"],"price":46,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:34.311Z"},"share_url":"https://firestarter.network/l/lst_qt0qcCQ_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
