My helmet specs

[rotor]

I got a fair bit of good advice, but it was a mistake on my part to engage in editorializing and pointless elaboration of my preferences. So, please ignore all my previous posts in this thread and imagine the opening post read simply thus:

I am looking for a light full-face helmet. If you happen to have one that weighs less than 1250 grams (2.75 pounds) could you please let me know the make and model, and where was it purchased?
