ALOHA! Thank you for stopping by and visiting KAST Fitness Wear - Authentic Brazilian

Brought to you by Summer Peters (Hawaii) and Amber Withycombe (Texas), these sisters have teamed together to share their love of health and fitness with others. KAST was discovered during a family trip to Brazil. While Summer was shopping in a small Brazilian town with her husband Eduardo, they found a cute boutique full of fun, colorful fitness wear. They fell instantly in love with the feel, stretch, durability, and colors and decided to share the Brazilian flare with the rest of the world.

CONCEPT: KAST is a fitness line from southern Brazil which can inspire and motivate you to feel your best in any sport or activity. KAST pants embrace comfort and style. The fun colors and patterns will get you through your hardest work out and then keep you stylish throughout the day.

FABRIC: KAST selects fabrics with quality and comfort as the top priority and works with a few different fabrics. All are soft, comfortable and form fitting. KAST material has proven: strength, colorfastness, soft touch, cooling effect, moisture absorption, quick dry, and durability. To learn more check out KAST Material and Sizing.

DEVELOPMENT: All KAST Fitness Wear comes direct from the KAST factory in Brazil which is a family run factory that provides a safe and healthy work environment to every employee.
