Founder and CEO Danh Tran’s love for design started at a young age, growing up working in his family’s small tailor shop. After 20 years as a designer, he realized he hated wearing stiff and scratchy dress shirts. So he invented Buttercloth®, a revolutionary fabric made of long fiber cotton. The "World's Most Comfortable Shirt" captivated the attention of Shark Tank's Robert Herjavec, and together they are making history.
Danh’s cutting-edge inventions, Icy Cotton® and Icy Bamboo™, are infused with organic mint fibers. You can instantly feel the cooling power when you put them on.
Welcome to the world of comfort.
“Amazing fabric technology.”
