The Apollo A7L Spacesuit

Designed for the harsh environment of the lunar surface, the Apollo A7L spacesuit was used for Apollo 7 through Apollo 14 missions and is the same type of suit worn by the Apollo 11 astronauts. Safety and mobility were key factors in the A7L's design. Previous American suits received life support from the spacecraft via long umbilical hoses. The A7L's self-contained life support backpack made such hoses obsolete, increasing the astronaut's mobility on the lunar surface. The A7LB suit was designed for use on the Lunar Rover on Apollo 15 through 17.

The suit was made from 21 different materials in 24 layers. These layers provided a seal to keep breathable air and pressure around the astronaut, rejected heat and radiation, actively cool and prevent abrasions, tears, and punctures. With the Portable Life Support System backpack, the A7L weighed nearly 200 pounds (90.7 kilograms) but allowed astronauts to work untethered on the Moon for up to six hours.
