Anyone on here own one of these newer style oxygen helmets?  Did you find it to be an upgrade from the original helmet?  Any issues with the newer style?  Are they as airtight and warm when the vents are closed up? Considering an upgrade and looking for feedback.  Overall have been very happy with my original oxygen helmet.

YEAH BABY!!!!

I'm getting about 1200 km to a fill up with my 3.0. Coming from a godzilla super duty, the fuel savings is quite a bit 

ELECTRIC is the way !!!!  

Unfortunately when you factor in all the maintenance and repair costs of modern diesels with the emissions BS, all those savings you thought you had disappear.
