Hi,
I'm Naomi and I own Bonehead along with Chris Frisella. Long-time lurker and thought I'd join to answer a couple of the questions posed here.
First, I hope your friend has a speedy recovery - that's a pretty nasty one!
Open cockpit - we have several open-cockpit pilots wearing our helmets, though in an open cockpit I would recommend going with ANR. The helmets all come pre-wired for CEPs, which can be used with the helmet both with and without ANR. With the ear buds in coupled with the ear cups and helmet on, you'll be amazed...
Liner system - the liners are removable, washable and adjustable. For the PilotX, small thru large is one shell and XL and XXL are another. The liners can be easily adjusted by adding and removing foam shims (which will also conform to your head after a few uses). The ear cups are also adjustable via screws on the side of the helmet, so the helmet can be easily resized within the sizes of its shell. The Aries is one shell sizes ad currently does not accommodate XXL.
There are a lot of configuration options and customization we can do for our helmets, so feel free to call/email if you have any questions at all.
And thank you to our Boneheads out there referring your friends - it's much appreciated!
Naomi
