What is your underwear made of?

We currently offer two styles of underwear, Cotton Modal and Seamless. All of our underwear (cotton modal and seamless) contains a percentage of modal, which is beechwood tree pulp spun into a yarn. It’s considered a semi-synthetic because the raw material is plant cellulose, but is rigorously processed.

Not only is modal incredibly soft, it’s a fabric with moisture-wicking agents that gives modal a cool hand-feel and doesn’t shrink. Or fade.


We offer our Cotton Modal style to both men and women. While Cotton reduces the slickness of modal, it increases modal’s absorbency.

Our Seamless style, made of modal and nylon, is currently available for Women. Modal reduces the synthetic feel of nylon while increasing durability & pilling resistance.
