System (Sequential Density Construction) to deliver certified protection against both linear and rotational impact forces. Offered here in a clean gloss white finish, it holds full UNECE 22-06 approval — the most stringent homologation standard in modern motorcycling — and is ready to perform from the morning commute to the race circuit.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eUNECE 22-06 certified: meets the highest current impact safety standard for road and competition use\u003c\/li\u003e\n\u003cli\u003eS.D.C.

Four discrete shell sizes ensure that every head circumference is housed in a shell shaped for it — not stretched or padded to fit — which has a direct bearing on both comfort and crash performance.\u003c\/p\u003e\u003cp\u003eInside, the fully removable and washable liner uses PROTX2 antimicrobial technology to resist bacteria build-up during hard sessions. The new liner retention net keeps the interior neat and prevents any movement of the comfort padding during use. The double-D ring retention system provides a secure, proven closure that meets race-day requirements, while the EPS-lined chin bar adds an additional layer of protection at a vulnerable point of impact.\u003c\/p\u003e\u003cp\u003eThe helmet is also prepared for hydration system compatibility, with an integrated Camel-Bag routing so long-distance or endurance riders can drink on the move without modification.\u003c\/p\u003e\u003ch2\u003eVentilation\u003c\/h2\u003e\u003cp\u003eA five-inlet, six-outlet ventilation architecture moves air from the chin bar and forehead intakes across the skull, exhausting heat and humidity through the rear. The integrated ventilated spine protector continues this airflow management down the back of the shell, reducing heat build-up on track or in summer traffic.\u003c\/p\u003e\u003ch2\u003eFitment and Sizing\u003c\/h2\u003e\u003cp\u003eTo find your correct size, wrap a flexible tape measure approximately 1 cm above the ear at the widest point of the skull and consult the size chart below. The J-GPRF is not a one-size-fits-all shell: the four shell and four liner size combinations mean the physical dimensions change between sizes for a truer anatomical fit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eXS: 53–54 cm\u003c\/li\u003e\n\u003cli\u003eS: 55–56 cm\u003c\/li\u003e\n\u003cli\u003eM: 57–58 cm\u003c\/li\u003e\n\u003cli\u003eL: 59–60 cm\u003c\/li\u003e\n\u003cli\u003eXL: 61–62 cm\u003c\/li\u003e\n\u003cli\u003eXXL: 63 cm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eJust1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eJ-GPRF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003e6130320181000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApproval\u003c\/td\u003e\n\u003ctd\u003eUNECE 22-06\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShell material\u003c\/td\u003e\n\u003ctd\u003eMulticomposite Fibre\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1,600 g +\/- 50 g (size M)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eGloss\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRetention system\u003c\/td\u003e\n\u003ctd\u003eDouble-D ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnti-fog visor\u003c\/td\u003e\n\u003ctd\u003eYes (Pinlock included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRemovable lining\u003c\/td\u003e\n\u003ctd\u003eYes, fully removable and washable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVentilation\u003c\/td\u003e\n\u003ctd\u003e5 intake \/ 6 exhaust ports\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHydration compatible\u003c\/td\u003e\n\u003ctd\u003eYes (Camel-Bag routing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e1x Just1 J-PGRF helmet\u003c\/li\u003e\n\u003cli\u003e1x clear visor\u003c\/li\u003e\n\u003cli\u003e1x Pinlock insert\u003c\/li\u003e\n\u003cli\u003e1x dark visor\u003c\/li\u003e\n\u003cli\u003e1x nose cover\u003c\/li\u003e\n\u003cli\u003e1x premium helmet bag\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Just1","offers":[{"title":"XS \/ White","offer_id":53167798190346,"sku":"6130320181000-01","price":359.1,"currency_code":"EUR","in_stock":true},{"title":"S \/ White","offer_id":53167798223114,"sku":"6130320181000-02","price":359.1,"currency_code":"EUR","in_stock":true},{"title":"M \/ White","offer_id":53167798255882,"sku":"6130320181000-03","price":359.1,"currency_code":"EUR","in_stock":true},{"title":"L \/ White","offer_id":53167798288650,"sku":"6130320181000-04","price":359.1,"currency_code":"EUR","in_stock":true},{"title":"XL \/ White","offer_id":53167798321418,"sku":"6130320181000-05","price":359.1,"currency_code":"EUR","in_stock":true},{"title":"XXL \/ White","offer_id":53167798354186,"sku":"6130320181000-06","price":359.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/50201107038474_tp.png?v=1785155459","url":"https:\/\/inter-pace.com\/en-eu\/products\/just1-j-gprf-racing-helmet-solid-white-glossy","provider":"Inter-Pace","version":"1.0","type":"link"}
