havent tried or seen the future helmets before, they do look lightweight compared with the gecko.
We use the communicater out on the rigs http://www.comunicator.co.uk/helmet_html/helmets.htm
we had to go for the beta+ as they allow for any type of headset ...although looking at the site its for aviators ......i wonder who picked that
I have also looked at the caberge range of helmets (breeze) in particular ...looked lightweight and has vents and used by quite a few RB 08 entrants.
If you get one do let us know how you rate it ....if you cant find a review theres a prompt to be the first
