{"product_id":"alpinestars-bionic-rib-protector","title":"Alpinestars Bionic Rib Protector","description":"\u003cp\u003eThe Alpinestars Bionic is a karting rib protector for 4 cycle racing, including club and regional Briggs LO206, when you want a shell under the suit and the series does not require an FIA 8870 vest. The product FAQ states it plainly: this protector is not FIA 8870 certified.\u003c\/p\u003e\u003cp\u003eThe shell is a high-density, impact-resistant PE hardshell with a fiberglass core in the protectors, and internal bio-foam. Padding is dual composition: a 3 mm high-density poly-foam layer laminated with 4 mm EVA. The outer is 500 denier Cordura for abrasion. The inner is soft poly-lycra, so the piece can sit under clothing or over it. A perforated rear and the ventilated build are the airflow. None of that adds an FIA stamp.\u003c\/p\u003e\u003cp\u003eFit is adjustable. A central back panel uses Velcro. The front strap closes with a D-ring and has an elastic section. Shoulder straps are breathable 3D mesh with an elastic gusset. The shape is contoured to sit under a kart suit, and the FAQ says it is available in adult and youth sizes. Check the size chart against chest measurement. A vest that digs into the ribs or rides up is the wrong size for that driver, and a loose seat lets you move no matter which shell you bought. Try the fit. Do not assume one brand's shape matches your rib cage.\u003c\/p\u003e\u003cp\u003eUse this Bionic when you want that ventilated bio-foam shell and elastic straps for club karting. The \u003ca href=\"\/products\/alpinestars-ak-1-kart-body-protector\"\u003eAlpinestars AK-1 Kart Body Protector\u003c\/a\u003e is the other rib protector from this brand, and it is the one homologated to FIA 8870-2018, with a thermoformed shell and energy-absorbing foam. Pick the AK-1 when the class or the organizer requires the FIA rib standard. Pick the Bionic when the FAQ's non-certified club protector is the one that matches the rulebook you are running.\u003c\/p\u003e\u003cp\u003eA kart rib vest only helps if it stays where the size chart put it. Swift Karting stocks the Bionic for LO206 club racing.\u003c\/p\u003e\u003ch2\u003eSizing\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0647\/9242\/8763\/files\/ALPINESTARS-BIONIC-RIB_PROTECTOR-SIZE-CHART_IMAGE.png\" alt=\"Sizing chart\"\u003e\u003c\/p\u003e","brand":"Competition Motorsport","offers":[{"title":"Black\/Red \/ Youth (One Size)","offer_id":54494444585278,"sku":"6547013-13","price":179.95,"currency_code":"USD","in_stock":true},{"title":"Black\/Yellow \/ Youth (One Size)","offer_id":54494444618046,"sku":"6547013-155","price":179.95,"currency_code":"USD","in_stock":true},{"title":"Black\/Red \/ Adult\/S-L","offer_id":54494444650814,"sku":"6537013-13-S\/L","price":199.95,"currency_code":"USD","in_stock":true},{"title":"Black\/Red \/ Adult\/XL-3XL","offer_id":54494444683582,"sku":"6537013-13-X3X","price":199.95,"currency_code":"USD","in_stock":false},{"title":"Black\/Yellow \/ Adult\/S-L","offer_id":54494444716350,"sku":"6537013-155-S\/L","price":199.95,"currency_code":"USD","in_stock":true},{"title":"Black\/Yellow \/ Adult\/XL-3XL","offer_id":54494444749118,"sku":"6537013-155-X3X","price":199.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0962\/4721\/8494\/files\/alpinestars-bionic-rib-protector-RED_BLACK_IMAGE.jpg?v=1790144574","url":"https:\/\/swiftkarting.com\/products\/alpinestars-bionic-rib-protector","provider":"Swift Karting","version":"1.0","type":"link"}
