Quick question, once you get a barding at level 10 (any tree), are you stuck with that specific barding until you reach level 10 on another tree?

I assumed that if you re-spec, the old tree's barding disappears and you get the up to date tree's barding instead. I just re-specced my choco from tank to dps hoping to change it up a little, but I've still got the paladin barding.
