The real question is whether you can use rotation when putting on a helmet or a knit hat - or can the employer require tipping?
But how does one calibrate the hat and/or helmet. This question has kept me up many nights. I have also seen some with hats on under thier helmets. Does this require special tools or is it accpetable to simply calibrate the hat first, then the helmet? Is there a difference for cotton vs. tech-wick vs. wool?
I am not sure why you are asking for a ski specific ski helmet. The Grio Remedy about the only difference I see is the goggle strap. Which I find funny since most bikers that use a full face wear goggles and the strap is not needed.
If I were you I would look at full face helmets from helmet manufactures that make mountain bike full face helmets. 661, Giro, Bell, Troy Lee, are some of the few. These helmets are not DOT rated so they are lighter weight and will work for skiing just fine.
For me if I am in a situation where I want a full face I will just grab the helmet I use for DH that is DOT and ECE certified.
