Special underwear which protects against temperature extremes, such as those found on Ortega. Roger Wilco acquired a pair on Phleebhut during the incident with the Pirates of Pestulon, and used them on Ortega to investigate the Pirates' massive cloaking field generator.

The Old Scratch brand produces a line of thermoweave underwear.

Behind the scenesEdit

  • An Easter egg in Space Quest IV lets the player travel back in time to Ortega, circa Space Quest III, where they immediately melt to death upon exiting the time machine, thanks to Roger no longer wearing the protective Thermoweave garment. Notably, the game misspells the word as "underware". Although given the high-tech nature of the underpants, that may have been another joke.
