i've beentrying to track down a catlike in N/A to no avail, but have found vendors in the uk and italy.

are there any issues in regards to the functional performance of their helmets in regards to well; saving my head?

i am not sure of what this disclaimer on one vendor's site is getting at:

"Important information for Customers Outside the European Union: The Kompact Pro Helmet is designed for use in the European pro peleton and therefore meets the EN1078 European safety standard. If your country requires a different and/or more stringent standard neither Prendas Ciclismo nor Catlike can take any responsibility for the use of the Whisper in these circumstances."

it refers to the "whisper" model, but this statement was present on the Kompact Pro listing as well.
