It has a hard torso and soft arms and legs, and a backpack of its own supplies oxygen and cooling water and removes carbon dioxide.",
      "The suit's soft parts are built from layers of fabric and film. The outer cover is Ortho-Fabric, which resists abrasion and tears and protects against micrometeoroids, tiny fast-moving particles. Five layers of aluminised Mylar insulate beneath it. The hard upper torso is fibreglass, and the helmet is clear polycarbonate."
