The Flash 3 tent, featuring Sierra Designs new ExoFusion technology (a new technology that combines external pitch and an integrated fly to speed set up and increase interior space), sets up in a matter of seconds, giving you a roomy, well-ventilated refuge in no time flat. The Flash 3’s integrated rainfly also allows this shelter to set up dry in the rain and substantially reduces overall weight.


  • ExoFusion - Exofusion shelters utilize an external frame combined with hybrid single and double wall panels, that allows us to create shelters unlike anything that has been seen or known before
  • Fast set-up - Because there is no separate fly to fuss with, an ExoFusion shelter sets up in far less time than traditional tents.
  • Dry set-up - Integration of the rainfly means your tent is protected during set up, rather than having the inner body get soaked before you can attach a separate flysheet.
  • Improved Ventilation - exoskeleton/hybrid wall construction allows vent placement and airflow planning that is not possible with traditional construction, so they stay dry and comfortable
  • Lighter - Hybrid walls, possible only with an exoskeleton frame, allow us to customize the tent interior with double walls where necessary, and single walls otherwise. Less material means a lighter shelter
