{"product_id":"ls2-ff901-advant-x-liner-carbon","title":"LS2 FF901 Advant X Liner Carbon","description":"\u003cp\u003eGenuine LS2 replacement interior for the FF901 Advant X carbon models, part 801901LNR01, available in every helmet size from XS to 3XL. The set carries the same specification as the original: X-Static© silver antibacterial fabric, laser-cut foam, hypoallergenic, breathable, removable and machine-washable.\u003c\/p\u003e\n\n\u003cp\u003eThis is the part that decides how long the helmet lasts you, and it is the part riders most often misdiagnose. Liner foam compresses under load and breaks down chemically from sweat and hair oils. As it does, the fit loosens: the helmet begins to move on the head, rocks under braking, and lets in noise that was not there before. The natural conclusion is that the helmet is finished. In fact the shell is untouched and the interior has simply reached the end of its service life — at a fraction of the cost of a new helmet.\u003c\/p\u003e\n\n\u003cp\u003eThe X-Static treatment is worth understanding. Pure silver is bonded to the fibre surface rather than applied as a coating, and silver is antimicrobial by nature, so the property survives washing instead of rinsing out after a few cycles. The foam behind it is laser-cut, which lets the density and profile vary within a single pad rather than being uniformly stamped — firm where the pad locates the helmet on your jaw, relieved over the cheekbone and where glasses arms run.\u003c\/p\u003e\n\n\u003cp\u003e🔑 Order the size that matches your helmet, not your head. And if the helmet is otherwise the right size but feels marginally loose at the cheeks, the cheek pads (part 806901CKP03) are the cheaper first step.\u003c\/p\u003e\n\n\u003ch3\u003eFits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLS2 FF901 Advant X Carbon\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003ePart\u003c\/em\u003e — complete replacement interior — crown liner and cheek pads\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFabric\u003c\/em\u003e — X-Static© silver antibacterial\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFoam\u003c\/em\u003e — laser-cut, varying density\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eProperties\u003c\/em\u003e — hypoallergenic, breathable, removable, washable\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSizes\u003c\/em\u003e — XS to 3XL\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart number\u003c\/em\u003e — 801901LNR01\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LS2","offers":[{"title":"XS","offer_id":53577238282506,"sku":"801901LNR01_XS","price":51.0,"currency_code":"USD","in_stock":true},{"title":"S","offer_id":53577238315274,"sku":"801901LNR01_S","price":51.0,"currency_code":"USD","in_stock":true},{"title":"M","offer_id":53577238348042,"sku":"801901LNR01_M","price":51.0,"currency_code":"USD","in_stock":true},{"title":"L","offer_id":53577238380810,"sku":"801901LNR01_L","price":51.0,"currency_code":"USD","in_stock":true},{"title":"XL","offer_id":53577238413578,"sku":"801901LNR01_XL","price":51.0,"currency_code":"USD","in_stock":true},{"title":"XXL","offer_id":53577238446346,"sku":"801901LNR01_XXL","price":51.0,"currency_code":"USD","in_stock":true},{"title":"XXXL","offer_id":53577238479114,"sku":"801901LNR01_XXXL","price":51.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/801901LNR01_00_59e29e44-b9af-4cc7-8b57-2d542fa05b05.png?v=1787836571","url":"https:\/\/inter-pace.com\/en-sv\/products\/ls2-ff901-advant-x-liner-carbon","provider":"Inter-Pace","version":"1.0","type":"link"}
