Thinsuit The thinsuit , sometimes known as Karflo Corporation thinsuit or Karflo ' s Thinsuit , was a light body armor that protected users against hostile environments including radiation , chemicals , pressure , temperature and vacuum , although it did not provide air . It was ineffective against direct attacks such as blaster bolts , but a thinsuit was so thin than a user could don a second armor over it . Through the years , thinsuits were used by professional scouts ; by the Cularin Militia during the Clone Wars ; and by the Alliance Special Forces during the Galactic Civil War , particularly Wilderness Fighters and the elite teams expert in fighting aboard starships . Description . The thinsuit was a one - kilogram outfit made of a very isolating , very thin material . It conformed tightly to the body of the wearer , being so snug that the wearer could don a second armor over the thinsuit . The thinsuit covered — and protected — all of the wearer ' s body except for the face . However , the thinsuit was provided with a face - covering breath mask featuring an extended filter that purified external atmosphere for six hours or provided one hour of internal air before running out . The suit also had easily - reachable storage pockets containing five more filters . The thinsuit was designed to protect the wearer from hostile environments . While it was useless against direct attacks such as blaster bolts , it provided isolation against limited exposure to radiation or to hostile chemicals in the atmosphere withstanding up to eighteen hours against most kinds of hostile atmosphere . It also protected against extreme pressure and temperatures from - 30 to 100 standard degrees . The thinsuit included an environmental system of small heaters and coolers that kept the wearer comfortable in these situations . The thinsuit endured puncturing , tearing and slashing . As it was also isolated against vacuum , it could be used as an emergency space suit . In that case , it provided heat and protection to the wearer for one hour , but it did not provide a means for the wearer to breathe . History . The thinsuit , developed by Karflo Corporation , was available for 900 during the last years of the Galactic Republic . The suit was alternatively known as Karflo Corporation Thinsuit , Karflo ' s thinsuit or simply thinsuit . During the Clone Wars , the Republic - aligned Cularin Militia stored several thinsuits among its arsenal of military gear , in preparation for an open conflict against its neighbor , the Thaereian system , which had joined the Confederacy of Independent Systems . In 22 BBY , the heroes of Cularin helped the Militia in a mission in the Ando system . In gratitude , the Militia offered the heroes some of their thinsuits , or any other item in their depot . During the later Galactic Civil War , thinsuits were worn by professional scouts , as these items were useful in their activities . The Alliance Special Forces , elite soldiers of the Alliance to Restore the Republic , also used thinsuits . Members of its 1st Regiment , experts in fighting aboard starships , found the armor very useful . Its 4th Regiment , the Wilderness Fighters , also enjoyed the isolation provided by the thinsuits . Thinsuits were available after the Galactic Civil War , during the Yuuzhan Vong War . Behind the scenes .
