Hey I was wondering if anyone has tried either the PI Cyclone or the Giro Ambient and could give me some feedback on it. I'll be biking in 30-45 degree weather and wanted to know if these could hold up. If anyone could tell me at what temperatures you've tried em at that would be great!

Giro rates the Ambient @ 40 degrees so those sound pretty decent.
PI does not rate the Cyclone at any temperature so I'm not so sure.

Both can be found for $35 online so price is not an issue. Any input would be appreciated.


Or if you've tried both and found that they both aren't good, do you have any other suggestions?
