Peter Nwrote a review of Giro Atmos II Helmet on October 29, 2015
Familiarity: I've put it through the wringer
This design certainly isnt new, but it shows how great it was when the original Atmos came out quite some time ago. Great ventilation, solid retention system, a fit that works well for me, and all at a lower price as this helmet has succeeded by others with snazzier options. I also own the Synthe and love it, but if you want the best helmet for your money this is it.
