{"product_id":"met-trenta-3k-carbon-helmet","title":"MET Trenta 3K Carbon Helmet","description":"The MET Trenta 3K Carbon is the most ventilated road helmet ever developed for the toughest races. Refined inside the Tube, MET's proprietary wind tunnel, this helmet is already a winner at the Tour de France and the Giro d'Italia Women. The Trenta 3K Carbon represents the ultimate expression of a modern road helmet, designed for an era where racing demands more speed, more control, and more protection.\n\nThe helmet features the 3K Airframe, a carbon wing structure that eliminates EPS from the internal frame. This innovative construction creates a continuous internal air channel uninterrupted from the front intake to the rear exhaust, ensuring consistent airflow at both high and low speeds. The design achieves a 40% improvement in the Virginia Tech test, the world's most recognized independent safety rating protocol, earning 5 stars and one of the best scores ever recorded.\n\nThe Trenta 3K Carbon combines an in-mold polycarbonate shell with an EPS liner and features 3K Carbon Technology, where a carbon cage is embedded into the liner to enhance shell performance. The helmet includes the MIPS AIR rotational management system, engineered to add protection while saving weight. With 24 external vents and optimized internal channeling, the helmet delivers a 16% increase in ventilation validated through thermal-cell testing in the MET wind tunnel.\u003ctable border=\"1\" cellpadding=\"5\" cellspacing=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eRotational Protection\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHelmet Certifications\u003c\/td\u003e\n\u003ctd\u003eComplies with the U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Head Circumference\u003c\/td\u003e\n\u003ctd\u003e56, 58, 61\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGender\/Age\u003c\/td\u003e\n\u003ctd\u003eAdult\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Head Circumference\u003c\/td\u003e\n\u003ctd\u003e52, 56, 58\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eBlack Matte, Blue Teal, Gray Gray, White Gloss\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003eLarge, Medium, Small\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVisor Included\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMulti Impact\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e260, 285, 320\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHelmet Style\u003c\/td\u003e\n\u003ctd\u003eTri\/TT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDefined Color\u003c\/td\u003e\n\u003ctd\u003eBlack, Blue, Gray, White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ekeyword search\u003c\/td\u003e\n\u003ctd\u003eSoftgoods Discounts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"MET Helmets","offers":[{"title":"Black Matte \/ Small","offer_id":52694350201106,"sku":"HE4953","price":539.95,"currency_code":"USD","in_stock":true},{"title":"Black Matte \/ Medium","offer_id":52694350233874,"sku":"HE4954","price":539.95,"currency_code":"USD","in_stock":true},{"title":"Black Matte \/ Large","offer_id":52694350266642,"sku":"HE4955","price":539.95,"currency_code":"USD","in_stock":true},{"title":"Blue Teal \/ Small","offer_id":52694350299410,"sku":"HE4959","price":539.95,"currency_code":"USD","in_stock":true},{"title":"Blue Teal \/ Medium","offer_id":52694350332178,"sku":"HE4960","price":539.95,"currency_code":"USD","in_stock":true},{"title":"Blue Teal \/ Large","offer_id":52694350364946,"sku":"HE4961","price":539.95,"currency_code":"USD","in_stock":true},{"title":"Opal Gray \/ Small","offer_id":52694350397714,"sku":"HE4962","price":539.95,"currency_code":"USD","in_stock":true},{"title":"Opal Gray \/ Medium","offer_id":52694350430482,"sku":"HE4963","price":539.95,"currency_code":"USD","in_stock":true},{"title":"Opal Gray \/ Large","offer_id":52694350463250,"sku":"HE4964","price":539.95,"currency_code":"USD","in_stock":true},{"title":"White Gloss \/ Small","offer_id":52694350496018,"sku":"HE4956","price":539.95,"currency_code":"USD","in_stock":true},{"title":"White Gloss \/ Medium","offer_id":52694350528786,"sku":"HE4957","price":539.95,"currency_code":"USD","in_stock":false},{"title":"White Gloss \/ Large","offer_id":52694350561554,"sku":"HE4958","price":539.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0684\/3534\/5682\/files\/da1215465a788b41cc20ccd957d3ee5e3794b21e.jpg?v=1788982757","url":"https:\/\/lennysbikeshop.com\/products\/met-trenta-3k-carbon-helmet","provider":"Lenny's Bike Shop","version":"1.0","type":"link"}
