The Germans designed a full pressure suit of laminated silk and rubber, with a reinforced net of silk cord. Several models were covered with a metallic outer covering to prevent ballooning. Suit pressures of 0.75 bar were achieved without 'sacrificing mobility', but the suit was very heavy. By the end of the war suits were in use with separate oxygen breathing and suit gas systems.
