About our brand
"With Fortress, you can wear less layers of clothing, and have less weight with a more dynamic temperature range. You can go from it being 50 degrees and jump into frozen Arctic water and have it be 20 degrees or 30 degrees outside and still feel comfortable.
-- Outdoor Media Company Owner
"The Fortress base layer was a game-changer. It allowed us to film on days that we normally wouldn't have been able to and we could stay out in the cold longer than the camera equipment could handle. That's when I was really sold on it. The battery life in our camera gear couldn’t keep up with Fortress. This is next-level stuff."
"With other clothing, if you exert yourself at all and start sweating, you get cold. Fortress is incredibly unique. When you get wet, you stay warm.”
-- Outdoor Enthusiast
