A gorgeous 19 year old female pilot in over time, there have been two types of suits, partial pressure and full pressure; both accomplished keeping pilots alive at high altitudes. Partial-pressure suits are skin-tight and are meant to put pressure directly on the body in case of decompression at dangerously high altitudes. Trapped gas will expand in the absence of pressure; therefore, these suits constrained the human body with essentially a tight, non-breathing fabric. Full-pressure suits are basically a loose-fitting bag shaped like a human with rings at the wrists and neck to attach the gloves and helmet. If the cockpit depressurizes the suit inflates to maintain a safe atmospheric pressure around the occupant until the aircraft has reached a low enough altitude for the suit to deflate. Air pressure in the suit keeps an artificial atmosphere around the pilot instead of fabric stretched tightly across the skin.
