Klim X1 Alpha Patriot Helmet

The X1 Alpha Helmet is the pinnacle of adventure helmet technology, developed over nearly five years for optimal aerodynamics, weight distribution, noise reduction, and intuitive functionality. An advanced head protection system built with KOROYD technology absorbs impacts efficiently while managing heat better than any helmet before. New next-gen face shields provide optical Class 1 clarity, HD vision, UV protection, and new infrared heat shielding, all of which reduce fatigue. With a direct control ventilation system, including a defogger mode, X1 Alpha offers superior comfort and protection. Ride protected in the most groundbreaking adventure helmet ever built. Shell/Construction Carbon fiber hand-laid outer shell Shell construction process reduces imperfections and excess weight KOROYD + EPS shell construction optimizes impact protection and reduces heat absorption with direct ventilation through KOROYD structure and EPS channeling KOROYD structures crush homogeneously for better impact energy absorption Shell, peak visor, ventilation ports, gasketing, and liner system optimized for best-in-class aerodynamics and reduction in wind noise and vibration Peak visor engineered for on-the-fly angle changes with tool-free adjustment, removal, and reattachment Peak visor and rear spoiler designed to reduce drag, lift, and optimize directional-view control while riding at high speeds Titanium D-ring chin strap closure system Optics Clear & photochromic face shields included Tool-free face shield removal is fast & easy Eye port gasket engineered to reduce vibration, noise, and increase resistance to harsh weather conditions Face shield side plate mechanisms engineered to self-calibrate for tight sealing Included PINLOCK anti-fog lens insert optimized for X1 Alpha maintains optical class 1 clarity, huge FOV Photochromic face shield quickly transitions from dark to light Both face shields are optically correct and multi-thickness for minimized distortion UV400 protection on all shields Tinted & photochromic face shields feature infrared shielding to reduce heat buildup Helmet is goggles-compatible Safety ECE 22.06/DOT certified Ventilation 2 adjustable, water-resistant forehead intake vents 1 adjustable upper chin guard direct diffuser vent for face shield 1 adjustable lower chin guard direct vent for cabin interior 4 exhaust vents Fit/Comfort 4-ride-mode versatility: ADV, Dual-Sport, Off-Road, Street Channeled EPS + KOROYD construction for airflow and heat control Removable and washable moisture-wicking antibacterial premium Brrr Pro Cooling fabric lined cheek pads and crown liner Interchangeable/replaceable cheek pads and crown liner thicknesses within sizes Premium perforated goat leather trim on chin skirt and neck roll for comfort and reduced buffeting 3 shell sizes for optimal fit (XS-M, L, XL-3XL) 5 EPS sizes for optimal fit (XS-S, M, L, XL, 2X-3X) Recessed ear pockets for comm system speakers Key Features Exceptional safety from KOROYD + EPS and lightweight carbon fiber shell Huge FOV & great optical clarity for awareness and visibility Unbeatable comfort through heat management, low drag & quiet aerodynamics 4 ride-mode versatility: ADV, Street, Dual-Sport, Off-Road Tool-free face shield & peak visor HEAD CIRCUMFERENCE (cm) 53-54 55-56 57-58 59-60 61-62 63-64 65-66 HELMET SIZE XS S M L XL 2XL 3XL SHELL SIZE M L XL EPS SIZE S M L XL 3XL COMFORT LINER* XS S M L XL 2XL 3XL CHEEK PAD SIZES** XS - 40mm S - 35mm M - 40mm L - 35mm XL - 35mm 2XL -30mm 3XL -25mm * Comfort liners are color coded to the EPS that they fit into. **ALL cheekpads are interchangable between all sizes: REDUCTION SIZE (BELOW XS): 45mm EXPANSION SIZE (ABOVE 3XL): 20mm
