The Delta-10 Research Protective Suit (RPS) concept idea was conceived on the early 1920's by several Ural researchers who needed a way to experiment without exposing theirselves to unnecesary dangers,resulting overtime in 1921 to the goverment to begin fundings of the development,on 1925 it was almost completely developed.but its release was delayed because of the ongoing civil war and other external factors which lead to its final release in 1926. The suit is made by early stages of a teflon fyber reinforced by a sponge-like structured plastic.It has a headpiece to keep out corrosive gasses (that are too dense to just pass through the fyber) in case any minor accident occurs.It has also a gasmask to filter less dense gasses.
