Atmospheric Suits also known as "VacSuits" are a self contained atmosphere that maintains a constant air pressure and quality that allows for human life, while providing a small amount of radiation shielding. Used by most ships for Extra-Vehicular Activities (EVAs) when in space, they have also been used on planets where the native atmosphere is not conducive to human habitation, ie Strophios.

It is not uncommon for these suits to be used in laboratories as their tightly sealed environments allow for the handling of incredibly hazardous materials without a lot of the precautions necessary otherwise.
