Has anyone found the Carja Storm Ranger or Banuk Trailblazer outfits in game? Supposedly all of the Deluxe DLC, including both of these outfits, is included in the Complete Edition but I have not been able to find either of them.

The HZD Fandom wiki isn't being terribly helpful, just indicating that they can be bought from merchants, but merchants do have different tiers so maybe you need to find higher-tier ones.
