{"product_id":"grivel-mutant-helmet","title":"Grivel Mutant Helmet","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eBuilt to be the kind of helmet you forget you're wearing until it matters.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe Mutant's expanded polypropylene (EPP) shell handles impact absorption while keeping weight down, with an ABS reinforcement at the top adding extra resistance exactly where exposure to rockfall and ice is highest. The structure protects both the crown and sides of the head, and a built-in airflow path keeps ventilation consistent rather than trading protection for breathability. A minimal adjustment system trims bulk and lets the helmet pack down small when it's not on your head, and the design itself stands out — a symmetric hexagon-covered top paired with a different pattern on each side.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eEPP construction for effective impact absorption at minimal weight\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eABS top reinforcement increases resistance in high-exposure zones\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eProtects top and sides of the head while maintaining consistent airflow\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMinimal adjustment system reduces bulk and packs down small\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDistinctive symmetric hexagon top design with asymmetric left\/right pattern\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAvailable in three sizes for a precise fit across a wide range of head circumferences\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSize S\/M: 48–58 cm, 153 g\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMaterial(s): expanded polypropylene (EPP), ABS\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCertification(s): EN 12492, UIAA 106\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grivel","offers":[{"title":"Black\/Yellow \/ S\/M","offer_id":47921642864866,"sku":"210000098801","price":57.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0656\/3649\/9682\/files\/4_2048x_3f2072ab-c522-494e-8fcb-52e2ca3138b2.webp?v=1782765817","url":"https:\/\/climbonequipment.com\/en-us\/products\/grivel-mutant-helmet","provider":"Climb On Equipment","version":"1.0","type":"link"}
