{"type":"firestarter.listing","listing":{"id":"lst_C1wIbGsZ","product_name":"S1-V Riding Vest","category":"Men","description":"The S1-V Riding Vest is the only vest we make. That's it. Just one. We made it right the first time around and haven't needed another one since. We use the same award-winning fabric as we do in our S1-J riding jacket.  Our C-Change fabric is windproof, waterproof, shockingly breathable, and lined with an active climate membrane that opens when it gets hot to ventilate, and constricts when it gets cold to keep heat in. It also happens to be one of the most durable, rugged, all-weather fabrics on the market today. With simple care, it might outlast your entire cycling career. These are built to last forever, function properly, and be the essential layering piece in any cyclist's closet. This is not a seasonal throw-away vest. This is an investment in a well-built garment designed to keep you moving forward year after year. A refined fit, protection from the elements in all 4 seasons, total packability, and the best waterproof zippers in the world make the S1-V pretty much the best there is.\nDurability: Ultra High\nFabric: Synthetic Blend with Active Cimate Membrane\nCare: Easy\nFit: True to Size / Athletic\nBest For: All Season Layering","images":["https://cdn.shopify.com/s/files/1/0143/5202/products/400remastered.jpg?v=1680104385","https://cdn.shopify.com/s/files/1/0143/5202/products/s1-v-riding-vest-supernova-orange_frontcopy.png?v=1680104385","https://cdn.shopify.com/s/files/1/0143/5202/products/Search_State_grid1_c3b2866b-edcc-415a-9673-aaa75d8fbc0d.jpg?v=1647352634","https://cdn.shopify.com/s/files/1/0143/5202/products/vest400.jpg?v=1647352634","https://cdn.shopify.com/s/files/1/0143/5202/products/s1-v-riding-vest-navy_400.jpg?v=1648559802"],"price":225,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:40.294Z"},"share_url":"https://firestarter.network/l/lst_C1wIbGsZ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
