theres a place in the shopping mall when you come into breck if you stay right on US9 insted of going down main street, make a left at the light and in that strip mall there is a small place where they rent armada skis.
i talked to the guy about it i think it was like 15 or 20 if you have an epic pass. guy was super chill i went in to see if they had any last years stuff for sale, sadly only a pair of arg's but they rent the whole armada line there.
good luck.
i think christy sports also does powder ski rentals not sure if they do armada though.
