Whether you’re hammering flowing MTB singletrack, pushing hard on the road bike, heading out for a trail run or hiking fast-moving mountain terrain, these versatile sports sunglasses deliver clear vision and dependable protection all day long. The updated Twist Six design brings a sharper, more modern look while maintaining the secure fit and comfort the series is known for.\u003c\/p\u003e\n\u003cp\u003eAt the core of the Twist Six S HR V is Alpina’s advanced Varioflex lens technology, which automatically adapts to changing light conditions in seconds. As sunlight intensifies, the photochromic lens darkens automatically, then brightens again when cloud cover or shade rolls in, making these sunglasses ideal for mixed woodland trails, variable mountain weather and long days outdoors where light conditions constantly shift.\u003c\/p\u003e\n\u003cp\u003eThe highly curved half-frame design provides excellent coverage against wind, dust and trail debris while maintaining impressive ventilation. Optimised Airflow technology helps prevent fogging during hard efforts, while Fogstop coating maintains clear visibility when intensity levels rise. Hydrophobic lens treatment repels water, mud and sweat to keep your vision sharp in wet or demanding conditions.\u003c\/p\u003e\n\u003cp\u003eBuilt from lightweight yet durable TR90 materials, the Twist Six S HR V remains comfortable during long training sessions and endurance adventures. Adjustable cold-formable nose wings and Alpina’s patented temple inclination system allow you to fine-tune the fit and lens angle for greater comfort and stability over rough terrain.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnologies\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVarioflex:\u003c\/strong\u003e is a lens technology in which the lens tint automatically adjusts to the weather. The self-tinting (photochromatic) lens reacts to visible light. When exposed to radiation, chemical elements open up and create a flat, darkening effect. When the light intensity decreases, the chemical elements close and the lens becomes brighter again. This process takes seconds. The result: a lens for a wide variety of light conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVarioflex photochromic lenses automatically adapt to changing light conditions\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSlim fit designed specifically for narrower faces\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLightweight half-frame construction for comfort and ventilation\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eOptimized Airflow system helps reduce fogging\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFogstop coating maintains clear visibility during high-output activities\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHydrophobic lens coating repels water, dirt and sweat\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAdjustable nose wings for a secure personalised fit\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePatented temple inclination system adjusts lens angle\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDecentered lenses provide distortion-free vision\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDurable TR90 frame construction\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e100% UV-A, UV-B \u0026amp; UV-C protection\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIdeal for MTB, road cycling, hiking, running and dirt bike use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eArea of application - Variable conditions: cloudy, overcast, snowfall, sunny\u003c\/li\u003e\n\u003cli\u003eArea of application: Hiking, Ski Touring, cycling, MTB, running, beach and water sports\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLenses: Cat 1-3 reactive, Fogstop\u003c\/li\u003e\n\u003cli\u003eShape: Sport Wrap\u003c\/li\u003e\n\u003cli\u003eWeight: 24g\u003c\/li\u003e\n\u003cli\u003eFrame Type: Semicircle\u003c\/li\u003e\n\u003cli\u003eGlasses Width: 135mm\u003c\/li\u003e\n\u003cli\u003eFrame Material: thermoplastic polyamide (TR 90), thermoplastic rubber (TPR)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eStandard: EN ISO 12312-1:2013 + A1:2015\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Alpina","offers":[{"title":"Smoke\/Grey Matt","offer_id":57178075758965,"sku":"OP-GG-ATWISTSIXSHRV-S\/GM-C1-3","price":84.95,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1554\/2851\/files\/20700488_600x600_2x_385f4454-8d91-4848-a3b9-1ea423c52d83.webp?v=1778687165","url":"https:\/\/rockrun.com\/es\/products\/alpina-twist-six-s-hr-v-cat-1-3","provider":"Rock+Run","version":"1.0","type":"link"}
