When designing this line, Sparco studied the driver's sitting position to ensure ultimate fit and comfort. Shield RW-9 uses a seamless construction with ultra-soft stretchable material. There are two different woven materials in key areas; thin stretch Nomex for comfort and mobility as well as a double perforated Nomex for increased breathability and ultimate comfort.\u003c\/p\u003e\n\u003cp\u003eThe minimal seams are stitched flat with thin specialized thread for added comfort. All Shield RW-9 underlayer garments are treated with Sparco X-Cool® Silver which draws heat from the body surface to cool the driver. In addition to cooling the driver, X-Cool® Silver treatment has an anti-bacterial effect. The Shield RW-9 collection has pieces to fit every driver's style, including short-sleeved nomex t-shirts, long-sleeved nomex shirts, nomex pants, nomex balaclava, and nomex socks.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Both FIA and SFI Approved\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0647\/9242\/8763\/files\/FIA_Approved_Logo.png?v=1712790583\" width=\"226\" height=\"43\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0647\/9242\/8763\/files\/SFI-Logo.png?v=1712792745\" alt=\"SFI Approved\" width=\"102\" height=\"43\"\u003e\u003c\/p\u003e\n\u003ch2\u003eSparco Shield RW-9 Nomex Shirt Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThe Shield RW-9 line is both FIA 8856-2000 and SFI 3.3 homologated\u003c\/li\u003e\n\u003cli\u003eSeamless stretchable Nomex in key areas for mobility\u003c\/li\u003e\n\u003cli\u003ePerforated knit in key areas for breathability\u003c\/li\u003e\n\u003cli\u003eDesigned for comfort in the driving position\u003c\/li\u003e\n\u003cli\u003eMinimal external seams increase driver comfort\u003c\/li\u003e\n\u003cli\u003eX-Cool® Silver draws heat from the skin to cool the driver\u003c\/li\u003e\n\u003cli\u003eX-Cool® Silver has anti-bacterial effect\u003c\/li\u003e\n\u003cli\u003eAvailable in white or black\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparco S.p.A.","offers":[{"title":"Black \/ Extra Small\/Small","offer_id":43204090233051,"sku":"001764MNRXSS","price":199.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ Medium\/Large","offer_id":43204090265819,"sku":"001764MNRML","price":199.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ Extra Large\/2X Large","offer_id":43204090331355,"sku":"001764MNRXLXXL","price":199.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ 3X Large","offer_id":43204090364123,"sku":"001764MNRXXXL","price":199.0,"currency_code":"USD","in_stock":true},{"title":"White \/ Extra Small\/Small","offer_id":43204090396891,"sku":"001764MBOXSS","price":199.0,"currency_code":"USD","in_stock":true},{"title":"White \/ Medium\/Large","offer_id":43204090429659,"sku":"001764MBOML","price":199.0,"currency_code":"USD","in_stock":true},{"title":"White \/ 3X Large","offer_id":43204090462427,"sku":"001764MBOXXXL","price":199.0,"currency_code":"USD","in_stock":true},{"title":"White \/ Extra Large\/2X Large","offer_id":43969335787739,"sku":"001764MBOXLXXL","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/9242\/8763\/files\/Sparco_Shield_RW-9_BLACK-Nomex_Shirt.jpg?v=1748035738"},{"product_id":"stand21-porsche-motorsport-evo-v3-nomex-fireproof-shirt","title":"Stand 21 Porsche Motorsport Evo V3 Nomex Fireproof Shirt","description":"\u003ch1\u003eStand21 Porsche Motorsport Evo V3 Nomex Fireproof Shirt \u003c\/h1\u003e\n\u003cp\u003eOfficially-licensed Porsche Motorsport safety gear from Stand21 is now available at Competition Motorsport.
