A comfortable, road focused touring helmet with excellent optics, improved padding, and solid heat performance. Not worth full retail price, but absolutely worthwhile if you get a discount. Fit & First Impressions Trying the Klim Alpha X1 alongside the Schuberth E2 and Klim GT1 at Sportsbikeshop made the choice clear. Despite the tight entry caused by Klim s new padded collar designed to reduce wind noise the X1 immediately felt more comfortable once seated on the head. It it really does help with wind noise. Fit and comfort The updated padding holds the head and cheeks far better than the Krios Pro. With the Krios I needed larger cheek pads; with the X1, the stock fit is already secure with padding that is thicker and of a better quality. Entry and exit The collar is snug at first, but after a few days it becomes noticeably easier to get on and off. If you wear glasses, the X1 s arm channels are a welcome addition. Larger armed frames are slightly fiddly but still manageable. Ventilation & Heat Performance I rode in 46°C heat through the Pyrenees about as extreme as it gets for Mr average and the X1 held up impressively. Ventilation is good but not as strong as the Krios Pro. The helmet feels designed more for road touring than off road airflow. The chin vent brings in more air than expected, and the top vents work well at certain angles. Even in extreme heat, I never felt the urge to rip the helmet off. The visor has a heat repelling coating. real world experience speaks for itself: the helmet stays comfortable even when the temperature is brutal. Optics & Visor Performance The transition visor is one of Klim s best features, and it remains excellent on the X1. No distortion, even with prescription glasses. Fast reacting tinting. The peak has fewer vents than before, which you feel during shoulder checks. You still get the patterned effect on the transition lens when the visor is up, but it s minor and expected. Buffering settles down after a few days of riding, which is unusual but welcome. Build Quality & Features Klim clearly invested more in designing the X1 from the ground up rather than re branding an existing shell. Padding and interior materials feel premium and secure. Speaker pockets are now included. The only real disappointment is the switch from the magnetic chin strap to a traditional DD ring. The magnetic buckle on the Krios Pro was a game changer, and going backwards feels unnecessary. Value for Money Is it worth full retail? No. Is it worth it with £100 less? Absolutely and in true sports-bike fashion the helmet was discontinued. You re getting a helmet that s: Comfortable Stable at speed Excellent in heat Great for glasses wearers Built with noticeably improved materials Road focused and refined And tested 54 hours of touring with zero hotspots or pinching after only purchasing the helmet a couple of days before. Final Verdict The Klim Alpha X1 is a high quality touring helmet that shines in comfort, optics, and heat performance. It s not perfect ventilation is milder than the Krios Pro, the peak catches wind during shoulder checks, and the DD strap is a step backwards but overall it s a helmet you can trust for long distance riding.
