The Story
When Dale Lewis established Fortress Clothing, the company made a lightweight, breathable layer of insulation for clothing worn by the men and women who work in oil fields and on construction sites in temperatures that can dip to -50°F. And yet the clothing was still comfortable in indoor temperatures up to 60°F.
The Pitch on Shark Tank
Fortress Cold Weather Clothing appeared on Shark Tank (Season 11) in 2020.
