Wondering if anyone has the Frill Airfit X03 helmet or anyone heard of any reviews on it? Let ok’ing to purchase for the remaining of the cold season

Unless anything’s changed, HD branded helmets like the one you mention are just re-skinned HJC helmets. If you could find the original HJC helmet model you might have a better chance of getting a review online, and would probably save a few bucks if you bought the non-HD product too. Hope this helps mate. 

They started rebadging Bell Helmets about 12 months ago

HJC supply the more expensive FXRG helmet ... but check the manufacturer date inside as, I discovered, some sit around in the shops for years. Good point to raise for a discount.

This is the helmet, actually found out it’s equivalent is the Scorpion T510 helmet.
