These are the new cloaks that are currently available in the store on Bullroarer, Turbine's test server. I'm assuming these cloaks will come with the next update which should be sometime during this month. All cloaks are available as hooded and hoodless versions.
Completionists and collectors should also rejoice; the rare cosmetics that were previously only available from GM events and the seldom-run Angmar battlegrounds will be available in the store, as well as the elusive Helm of Rohan!
As usual, click for full size! Green denotes dyeable areas.
