My husband Eddie and I live on Maui, Hawaii and have our KAST pants handmade near his hometown in Brazil.

We have been going to visit family there for over 10 years. Each time we relish all of their high quality, soft, comfortable fabrics!

KAST combines our love for amazing fabric with our passion for fitness. These fitness pants fit great and provide freedom of movement. The fun colors and prints will get you through your hardest workout plus keep you stylish throughout the day.
