The suits have been exclusively designed to remain in pressurized environments so that they have a pressure similar to the Earth's normal atmospheric pressure.
In addition, the EVA suits will make it possible to work both inside and outside the capsules, as required, due to all the advances in material manufacturing, joint design, reinforced redundancy safeguards, as well as the integration of a helmet display with heads-up display (HUD).
Announced at the weekend, the suits will be worn by the four crew members who will take part in the Polaris program's first mission, Polaris Dawn.
Polaris Dawn won't be launched until the summer of 2024 and will mark the first commercial spacewalk, as well as the first spacewalk to simultaneously include four astronauts.
Mobility is the central focus of SpaceX's teaser video published on X on May 4, with a wearer of an EVA suit showing his ranges of movement of the fingers, shoulders and elbows.

According to Popular Science, SpaceX's EVA suits are made from a variety of textile-based thermal materials and include non-rigid rotary joints that allow them to work in pressurized and non-pressurized environments.
For the boots, the designers used the same temperature-resistant material found in the interstice of the Falcon 9 rocket and in the trunk of the Dragon capsule.

The Polaris Dawn astronauts will wear 3D-printed polycarbonate helmets with copper and indium-tin oxide coated visors, as well as anti-reflective and anti-fog treatments.
During the spacewalk some 690 km above Earth, each crew member's helmet will project a built-in display to provide real-time pressure, temperature and relative humidity readings.
Like the suits designed by Prada for NASA's Artemis III astronauts, SpaceX's EVA suit also aims to highlight a future in which all body types can live and work beyond Earth.
SpaceX explains that all updates to its EVA suits are adaptive in design, which will allow customization to accommodate "different body types, as SpaceX seeks to create greater accessibility to space for all of humanity".
