Pressure-Skin Weave

Spacesuits are expensive.

Evolution is cheaper.

Pressure-Skin Weave is a living biomaterial designed to supplement or partially replace conventional pressure garments. Originally developed for workers operating in marginal atmospheric conditions, the weave combines engineered connective tissues, flexible structural proteins, and microscopic pressure-regulating systems into a lightweight biological fabric.

When integrated into clothing or directly into engineered skin, the material provides remarkable resistance to pressure differentials while maintaining flexibility and comfort.

Various vacuum-adapted Clades eventually incorporated aspects of the technology into their own biology. In some populations, the distinction between clothing, equipment, and anatomy became increasingly difficult to define.

Pressure-Skin Weave did not eliminate the need for spacesuits.

What it did eliminate was the assumption that survival in hostile environments required carrying all of one's protection externally.

Sometimes the habitat comes with you.
