Cold Environment Suits are a UNSC Marine Corps uniform and equipment package worn in arctic environments. The suits were only seen in Halo Wars trailers and the game itself. The suit is colored white and gray, and has a balaclava and goggles that protect the wearer's face from the cold, and also appears to include a hood. The camouflage utilities themselves seem bulkier, thicker, and more insulated than the standard utilities wore by Marines deployed from the Spirit of Fire, but features identical armor plating.
