Guild Wars 2

When I unlock a certain piece of armor in sPvP I have noticed that once I customize that piece of armor with runes I cannot deposit it into my locker anymore and the collectible is no longer available in my locker as well since I withdrew it. I understand this is probably to stop people from mass salvaging armor for materials but is there a way to acquire the same armor from the vendor without buying dozens of chests and crossing my fingers once you have unlocked it?

If you un-equip the piece you should be able to re-deposit it, however it will strip whatever runes you put in it.
