brief description
A little more information on the suite that needs modification.
key insights
  • Liquid Cooling and Ventilation Garment
  • Underneath the suits, astronauts wear "Maximum Absorbency Garment" (MAGs) urine-containment trunks (resembling "Depends" incontinence shorts) and blue-colored thermal underwear, which has plastic tubing woven into the garments allowing for liquid cooling and ventilation, the latter being handled by a connector located on the astronaut's left waist. The pressure bladder uses a "breathable" material that, while maintaining pressure, allows perspiration to exit and prevents liquids from entering, this is an improvement over the non-breathable pressure bladder used for the LES.
