I am not affiliated with this site in any way. I just use it because they usually have great deals on clothes, sunglasses, watches and whatever. This is the first time I have seen helmets though.

Items usually stay up till gone, which is normally about 5-6 hours.

edit: the little bar indicators on the left say how many are left. They were both full about 10min ago

edit#2: They sold them all. Damn, that was fast. Didn't even last an hour
