Sorry, but I actually race mx and these are non-brand cheapo helmets that aren’t worth the asking price. You will not be able to find parts (like the visor, which will break on the first crash) and even if these were good helmets, you should ALWAYS try helmets on in an actual store. Correct fit is essential and there’s more to it that guessing what your head size is.
Sorry Woot, but these shouldn’t even be for sale here. Helmets are an important safety item for off-road riding (ATV, motorcycle or mountain bike) and fit, comfort, quality and meeting standards is important. The saying is: “If you have a $10 head, buy a $10 (or $35) helmet.”
There are good, readily-available quality helmets in the $60 to $99 range. These aren’t.

So what you’re saying is that you’ve got a $60 to $99 head? 
I agree with trying helmets on, they do vary quite a bit from brand to brand, and even models within brands. I must have a head shaped like a shark fin, as some Shoei’s crush my forehead, but have too much slop from side to side.
However, studies have shown that ANY helmet is far better than no helmet. Now you usually do get better material quality and fit and finish and features on more expensive helmets.
And any of these are far more protection than a typical bicycle helmet. A friend came off her bicycle (large pot hole in the road, hidden in shadows) and did the classic faceplant, resulting in a lot of work for dental and plastic surgeons. She observed that if she’d been riding her motorcycle, she’d have had her full-face helmet on, and been spared a lot of misery.
I guess that’s a long winded way of saying in for two for spares/loaners.
