I brought both, but can’t decide.
Just wondering what others have decided?
I’m wearing mine. I hadn’t considered not wearing it, even when the forecast high was in the 100s. Now that the forecast high for Sunday is now 90 degrees - so we’re talking low to mid 80s on the bike - I’ll need the aero helmet just to keep my head warm!

I am. I only brought my aero and I wore it at Muncie when it was like 90 and humid so I think I will be ok here. And, crossing my fingers, according to weather channel and accuweather it will only be around 90 until 2 and a high of 95. Now who on earth really knows but I figure if it ain’t broke don’t fix it so I’m sticking with my aero!
