Bolt Threads is harnessing proteins found in nature to create fibers and fabrics with both practical and revolutionary uses.

Our fabrics will provide more lightweight comfort and breathability—and be more sustainable—than the world’s most beloved fabrics like cotton, wool and traditional silk.

Our technology is programmable.
That means we can tune our fabrics to deliver specific benefits.

OUR TECHNOLOGY MOVES AWAY FROM:

  • Petroleum-based polymers
  • Toxic processes
  • Non-renewable materials

AND TOWARDS:

  • Closed-loop production
  • Sustainable fabrics
  • More renewable solutions

We’re making fabrics that are better in every way, for everything from the fashion runway to the running trail.
