- Udo 13y agoMy guess would be that full pressurization makes the suit too rigid.
- jbri 13y agoThe ISS is pressurized to match Earth at sea level (it's designed for long-term habitation), and the pressurized modules are built to withstand that pressure. Making a spacesuit that could handle the same pressure would require it to be much heavier and more rigid. Cutting the pressure makes it much easier to work in.

He struggled to move inside his stiff suit.
