What the Prada–Axiom Liquid Cooling Garment Is
The Liquid Cooling and Ventilation Garment (LCVG) co‑developed by Prada and Axiom Space is a form‑fitting inner spacesuit layer that circulates chilled water and fresh oxygen next to an astronaut’s skin, stabilizing body temperature and breathing during long, demanding moonwalks inside NASA’s Artemis AxEMU spacesuit. Worn as the innermost “safety suit,” it is the first piece astronauts step into before sealing into the outer shell of the Axiom Space suit design for Artemis missions. Light gray, stretchy fabric follows the body’s contours while clear tubing maps over the torso, arms, and legs, finished with a subtle red stripe that nods to Prada’s performance wear heritage. Although it is hidden from view, this layer is central to astronaut thermal protection, directly influencing comfort, alertness, and safety during NASA moon mission suit operations that may last up to eight hours on the lunar surface.
Why Astronauts Need Liquid Cooling on the Moon
On the Moon, astronauts work hard but cannot cool themselves the way they do on Earth. In a vacuum, sweat does not evaporate and there is no air to carry heat away, so metabolic heat from walking, lifting, and operating tools can build up quickly inside a closed NASA moon mission suit. The Prada spacesuit Artemis inner layer solves this with a dense network of fine tubes stitched into the LCVG. Cold water flows over major muscle groups, absorbing excess heat as the astronaut moves. That warmed water then travels to the portable life support system (PLSS) on the back, which releases the heat into space. According to Axiom Space, the LCVG “functions as an internal ‘safety suit’ worn directly against the astronaut’s body,” keeping internal conditions stable even during demanding Artemis surface excursions.
Redundant Cooling and Clean Air: Life Support by Design
The LCVG’s liquid cooling ventilation garment system is built around two independent cooling loops. The primary loop handles most of the heat removal, while a second, fully operational loop runs in parallel. If the main system fails, the backup takes over without interrupting cooling, avoiding a single point of failure during Artemis moonwalks far from quick rescue. At the same time, a separate ventilation circuit manages breathing inside the helmet. Fresh oxygen is flushed across the astronaut’s face, while exhaled carbon dioxide is drawn into the PLSS. There, scrubbers remove CO₂ and the cleaned oxygen recirculates. This constant airflow prevents pockets of CO₂ from forming near the mouth and nose, which could otherwise impair performance. Together, fluid cooling and controlled ventilation turn the inner Prada spacesuit Artemis layer into a quiet, continuous life-support partner rather than mere clothing.
Prada’s Textile Craft Meets Axiom’s Engineering
The AxEMU LCVG is also a story of fashion and aerospace solving the same problem from different angles. Prada brings experience in advanced textiles, engineered knitting, and precision garment construction, while Axiom contributes spaceflight systems engineering and life-support expertise. Using 3D modeling and engineered knitting, the team created a single, continuous garment with minimal bulky seams, improving comfort and freedom of movement under the rigid outer Axiom Space suit design. The light gray, body‑-hugging silhouette keeps the liquid lines close to the skin for efficient heat transfer, and the single red sleeve stripe subtly connects the LCVG to Prada’s activewear lineage. “By bringing together the best in both aerospace engineering as well as luxury craftsmanship and advanced product development, we have developed a garment that neither company could have created independently,” said Axiom CEO Jonathan Cirtain.
The Future of Fashion–Grade Engineering in Space
For Artemis IV and later missions, astronauts will spend more time working on the surface than during earlier lunar programs, which raises the bar for comfort and reliability in every NASA moon mission suit component. The Prada–Axiom LCVG shows how borrowing methods from high‑end sportswear can improve astronaut thermal protection without sacrificing safety. Seamless, body‑mapped construction supports long, eight‑hour spacewalks, and the redundant cooling system reflects a broader Artemis philosophy that mission‑critical systems cannot rely on a single layer of protection. As space agencies and private companies plan extended lunar stays and, eventually, work in even harsher environments, the liquid cooling ventilation garment points toward spacesuits that are both high‑performance equipment and carefully engineered clothing, where fashion‑grade materials, fit, and detailing help keep crews alive far from home.
