Modal What is Modal? Modal is a natural fiber made of 100% beech wood cellulose. It is silky soft and has a natural luster that doesn't wash out. Modal is 50% more absorbent than cotton and dries more quickly. Even after numerous washings, fabrics made with modal remain soft and silky, the colors bright and shiny. Modal is gentle to the skin and provides highest comfort. Millennium towels by Bonjour of Switzerland are 100% modal. Millennium towels have a cult following and are often featured in magazines. They've been featured in Oprah magazine's "The O List" and New York Magazine's "Best Bets".
