Life support gear
Life support gear was technology for assisting with survivability in inhospitable environments.

After the disappearances of Captain James T. Kirk and Helmsman Hikaru Sulu near the rogue planet Gothos in 2267, Spock requested geophysical findings of the surface below. There was no detectable soil or vegetation, temperature was extremely hot, it had a toxic atmosphere swept by tornadic storms, continuous volcanic eruptions, and deadly to any lifeform as they knew it without oxygen and life support systems. The estimated survival time of two unprotected individuals was not very long. Spock ordered DeSalle to equip the landing party with full communications, armament, and life support gear. After beaming down to the surface with breathing masks, they realized the situation was not as indicated by starship sensors. There were no storms and the atmosphere was exactly the same as theirs.
