The standard flight suit was designed with space travel in mind; it's produced from an industrial-strength synthetic polymer which allows for maximum flexibility while maintaining its pressure in the vacuum of space. When used in conjunction with the standard flight mask, which locks into place via fitted grooves in the collar of the suit, it has been reported that one may survive for up to 48 hours in a vacuous environment.
The suit contains a simple re-breather within its lining, which takes useful particles from a sentient's exhaled breaths and reuses them to allow the being to continue breathing. This apparatus will generally allow any being to survive for up to the reported 48 hour period, after which time the useful particles being exhaled are so few that it is impossible to sustain life.
The suit can be custom tailored for any species and, for an extra cost, can come in any colour desired.
