The secret to UnderFit’s superior comfort starts with the fabric. We use a luxurious, sustainably sourced TENCEL™ fabric blend. It feels great against your skin, provides all-day comfort and is built to last.
Our products are made from the perfect combination of Lenzing TENCEL™ Modal and Lyocell, two incredibly resilient semi-synthetic fibers knit together to create undershirts that are breathable, move with you all day, and retain their shape for years to come. You’ll never want to go back to cotton.
