Review Image by Jason
For the past year my primary cycling helmet has been a Giro Aeon. That is the basis for the following review & comparison. I only bought this helmet for the visor and therefore have not worn it on any rides without the visor. I've taken it out on 4 rides, for 100+ miles, one of which included a 889' climb with 4% decent. I've been an avid cyclist for over 20 years and can be a little critical when it comes to my cycling gear. Overall I give this helmet 4 out of 5 stars because it's not perfect right out of the box. Aerodynamics (5 of 5): Winds in my area have been 5-10 mph this summer hence the desire to purchase an aero helmet. My first ride with this helmet was on a day with 10-15 mp winds. About two miles into my ride it occurred to me there was a noticeable reduction in drag compared to the Giro Aeon. I reach 41 mph at a full sprint riding on a road with a 45 mph speed limit in between my house and my favorite cycling trail. As this is my first aero helmet, I am very pleased with reduction in air resistance. Airflow (3.5 of 5): The videos on the Giro website presented some interesting airflow and wind tunnel tests that had me very optimistic about the cooling effects. In reality, the Giro Aeon is noticeably cooler and will remain my go to helmet on hot days when there is no forecasted wind. During the months of July and August, it is typically 85-100 degrees with 75%+ humidity. Very miserable cycling conditions. The visors deflection of the wind also blocks some of the air flow that would come up from underneath the helmet. When riding with the visor you are solely depending on the four vents to bring in air. I've discovered I have to hold my head at a very specific angle to maximize the airflow. During the Fall, Winter and Spring, this is not going to be a concern. I anticipate loving this helmet fall through spring. Unless there is snow or ice on the road/trail, I continue to ride down to 20 degrees. Reduced airflow is going to be a blessing. Style (3 of 5): Giro typically makes their helmets with some pretty nice color schemes. For a $275 helmet, the designers could have put a little more effort into the appearance. I had a very hard time picking a color. I didn't like the black for safety reasons. I prefer helmets that provide something that helps vehicle drivers spot me on the road. The white was very plain. I settled for the white and spent a couple days airbrushing some metallic silver strikes with a translucent black fade. I'm not the best at airbrushing so it's not perfect and might not withstand the test of time, but it looks a lot better in the meantime. Lens (4 of 5): Overall I am okay with the lens. I've not yet experienced any issues with fogging. So far the magnetic locks seem to be working quite well. The visor has a good field of view and does not overly interfere with my peripheral, vision which was a major concern. I would prefer a polarized lens but the glare off the road and trail surfaces hasn't been too bad so far with the lens that came with it. I wanted to order a clear lens so I could wear my polarized photochromic cycling glasses underneath, but replacement lenses are not cheap and hard to find. Buyer Beware: Giro does not sell replacement lenses. When I contacted Giro to ask about replacements I was sent the link to a separate website (Amazon won't let me post the website). Replacement lenses are $59.99, plus $5.00 handling fee for orders under $100. It would have been nice if the helmet could have been ordered directly from Giro with a choice of which lens you want with the helmet. In dark and low conditions, particularly in the winter, I will not want the lens that came with the helmet. I will have to order the clear lens so I can wear my polarized photochromic cycling glasses. It will be the winter that puts the anti-fogging to the test. I wear a balaclava under my helmet. Cycling glasses fog immediately when stopping from my breath. I'm hopeful the lens is far enough away to prevent that from happening. ... show more

Very happy, I can ride with glasses and visor. Was struggling for 2 years with different helmets. This one fits perfectly and no sliding down on my nose. update: broken shield, slash 1 star

    • Great Helmet!
Although it took a bit to get used to removing and reattaching the magnetic visor while cycling for wiping away perspiration, that was a tiny hurdle and I love this helmet with integral visor! No sunglasses required although the visor can be removed and sunglasses used if so desired. Very light weight, easy to adjust the strap to the right tension needed, and good visibility with the white portion of the helmet. Possibly a tad pricey, but the visor bought alone is $70, so $230 for a quality helmet to protect one's head is a very fair price. ... show more

    • Less Than Perfect
I do like this helmet. My critiques are two items. The lens, as others have stated, is extremely fragile. It will scratch with just a stern look at it. I’m very careful about my gear, but it shows two scratches on the lens no matter how careful I’ve been. I understand you can say that the fault is mine, but I really do take precautions, plus I read enough reviews to know how sensitive it is, so I WAS careful. Secondly, I have the large helmet and it is large. Large overall. When I put it on, its as if I have a basketball on my head and is subsequently not very stylish. Fortunately, I’m into function over form more these days, so I do wear it and from a helmet perspective, it’s great. Comfortable and it fits well. Just be aware that the lens will scratch and the replacements are overpriced because the coating is whisper thin. ... show more

    • Potentially unsafe.
It's adequate. The black on either end of the visor actually blocks some vision. This seems unsafe.
