Have had many helmets over the years including prior Lazer models. Fit is an individual thing for sure but this Lazer Z1 checked all the boxes for me. Best fitting helmet I have ever owned. I always wear a vintage cotton cycling cap under the helmet. The cut of the brim allows me to wear it comfortably with the brim up or down. Also fits the contour of my sunglasses. Straps and buckles are just right. I forget that it is even on my head after the first few miles and even after 50.
I wont speak to its aero advantage bc that needs to be tested in a wind tunnel on a specific rider. However, my last three triathlons with this helmet have corresponded with some of my top bike performances relative to competitors.
Yes, its a crazy looking thing like something out of "space balls."
The surprising thing to me is how comfortable it is. Well balanced. Ventilation is excellent, even with the vents covered. Visibility is excellent. It comes with two visors - a clear and a dark one. And of course a big case to carry it and both visors in.
I recently purchased a matte black Giro bicycle helmet, and I'm absolutely thrilled with it! The sleek, minimalist design looks sharp and modern, making it a standout on the road. The fit is spot-on, with Giro's adjustable ROC LOC system providing a secure, comfortable feel without any pressure points, even on long rides. It's lightweight yet feels incredibly sturdy, offering peace of mind with its top-notch safety features. The ventilation is fantastic'plenty of airflow to keep me cool during intense rides. The matte finish is not only stylish, but also resists scratches and smudges. Whether you're a casual rider or a serious cyclist, this Giro helmet is a perfect blend of form, function, and safety. Highly recommend!
Another great Kask helmet.. the style, fit, quality and aero benefits are the best around. I wear a large and the helmet fits great. Not 100% of the real world aero benefits, but it makes me feel and look faster.. Lol.. Safety, quality and protection are good also, no issues. Straps and internal pads are of high quality. My only complaint is the way the forehead sweatband accumulates sweat, otherwise its cooling on hot days is non-issue, plenty of air flow and sun protection.
