What the Prada–Axiom Liquid Cooling Garment Is and Why It Matters
The Prada–Axiom Liquid Cooling and Ventilation Garment is a form-fitting inner spacesuit layer that circulates chilled water and oxygen around an astronaut’s body to regulate temperature and breathing during long moonwalks in extreme lunar conditions. Unveiled in New York, the Liquid Cooling and Ventilation Garment (LCVG) is the innermost component of Axiom Space’s AxEMU suit for NASA moon missions, sitting directly against the astronaut’s skin. Light gray, stretchy fabric hugs the body in a streamlined silhouette while clear tubing traces mapped routes over major muscle groups. Beneath the outer protective shell, this layer quietly handles astronaut thermal regulation, carrying heat away from the body and sending it to the portable life support system for rejection into space. A dedicated ventilation loop bathes the face in fresh oxygen and clears exhaled carbon dioxide, turning the LCVG into the literal lifeline between human physiology and the vacuum outside.
How the Liquid Cooling Garment Keeps Moonwalkers in Their Thermal Comfort Zone
At the heart of this Prada spacesuit design is a liquid cooling garment architecture that treats the astronaut’s body like a thermal circuit. Cold water is pumped through a primary network of tubes laid over the torso, arms, and legs, absorbing metabolic heat as astronauts work through up to eight-hour spacewalks on the lunar surface. That warmed liquid then flows to the backpack-mounted portable life support system, where the heat is expelled into space. According to Axiom Space’s announcement, the LCVG “includes a fully redundant cooling circuit” so a second loop can take over if the main one fails, preventing dangerous overheating. Separate tubing manages ventilation, sweeping fresh oxygen across the astronaut’s face and moving carbon dioxide toward scrubbers. This tight integration of cooling and breathing systems turns the inner layer into a central piece of Axiom Space technology for future Artemis missions.
Prada’s Fashion Engineering Meets Axiom’s Space Hardware
The collaboration between Prada and Axiom Space stands out because it merges haute couture skills with aerospace engineering in a way that is unapologetically functional. Prada contributed advanced textiles, engineered knitting, pattern making, and precision garment manufacturing, along with specialized fibers that can be worn repeatedly on long-duration missions. These textiles are microbial-resistant and antifungal to resist odor and degradation between wears, a practical concern when astronauts cannot easily shower. Axiom Space brought life support integration, 3D modeling tools, and experience with NASA moon missions to design tube paths that balance cooling efficiency with mobility. Engineers iterated through several models, refining how the tube network sits on the body so astronauts can bend, reach, and climb over rugged terrain without kinks or hot spots. Even the single red stripe down one sleeve nods to Prada’s activewear heritage while preserving the AxEMU suit’s technical focus.
From Outer Shell to Skin-Closest Layer for Artemis Missions
This is not Prada’s first step into orbit-adjacent design. The two companies initially partnered on the AxEMU’s outer shell, which is built on NASA’s xEMU design and engineered for thermal extremes and micrometeoroid exposure at the lunar south pole. Extending the partnership inward to the LCVG made the Prada spacesuit design more cohesive from exterior to interior. The new inner layer will be one of the few barriers between astronauts and space, tailored for a wider range of crew members and for both lunar surface and microgravity operations. Axiom Space has said the LCVG is being readied for NASA’s Artemis IV mission, where extended moonwalks will be routine. By turning what used to be anonymous “long underwear” into high-performance infrastructure, the project signals a future where space gear borrows from fashion’s fit, materials science, and attention to the human body as much as from traditional engineering.
