I just finsished a 4 hour training ride in 75 - 85 sunny weather and it was perfect. This ride was in a particularly windy area and the helmet stayed very snug and comfortable. The visor sits wide and motionless across your face, securely attached by strong magnets. You get a wide and and sun protected view. I never felt hot or uncomfortable the entire time. Buy this helmet before the sale ends or they run out. This is my first aero helmet and may very well wear it for all my rides.
Fit and feel of the helmet is awesome. This is first TT helmet you can wear and not be burning up after 5 minutes. The wind flows thru it and is not bad to use in South Louisiana heat. The visor is leaps above the competition. I turn it up and warm upride to the start line and then turn in around and race.
