* SpaceX EVA suit mass not publicly disclosed. Significantly lighter than EMU due to umbilical-based life support (no backpack). Duration marked as "Umbilical" because life support is provided by the spacecraft, not the suit itself.

Frequently Asked Questions

Among IVA (launch/entry) suits, the Russian Sokol is the lightest at approximately 10 kg. Among EVA suits, the SpaceX EVA suit is likely the lightest because it offloads life support to the spacecraft via umbilical. Among self-contained EVA suits, the Apollo A7L was lighter than the EMU (91 kg vs 127 kg).
The Axiom AxEMU is being designed for 8+ hours of lunar EVA. The NASA EMU supports 6.5–8 hours. The longest actual EVA was 8 hours 29 minutes, supported by the EMU during ISS construction.
