Aviator goggles fitment with fox v3

I can't tell you about that Helmet but something to consider is that goggles might fit one face and helmet great in a large but in a XXL it won't fit, etc.

Find the helmet you like and then fit your goggles after. Most companies will usually be happy to exchange their product for a different model or size or even a full refund if you are not happy with them.

You can certainly ask a question like you did, but be aware that if someone has a medium helmet and a different nose their fit will be different on your large helmet. Nose makes a lot of different on goggle fit.

goggle fit comes down to head size, PD (pupil distance) and the nose generally.

Helmet fit usually comes down mostly to head size. Shape is a consideration but typically you can adjust that with the padding. You are mostly buying comfort and style with helmets. There was a study a while back by a former BELL engineer that showed that cheap helmets protect as good if not better for serious head injuries as expensive helmets. As price goes up, comfort also increases, along with venting. More expensive helmets typically protect against secondary injuries better as well, such as injuries from the chins trap causing abrasions and cuts.
