I have one and its nice. No issues with fogging but it MUST be connected to power or it will fog up bad.
I didnt have the older one to compare it to unfortunately.
I get the impression from a few buds who have owned both that the Flow is not as hot inside as the old one.
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.
