So had tried on one of the Spirit helmets (Torque model).
Made from fibreglass so really light. Can honestly not see why you'd take a Shark 700 over this specific one.
The other Spirit ones don't look like anything special.
Btw, if anybody cared, they're designed here but manufactured in China, India etc.
I have this one.

Been using it for about 10 months, haven't had any issues with it at all.
