In recent years, modal has taken the underwear market by storm—and for good reason. This soft, breathable, and durable fabric has become a favorite among consumers who value comfort, quality, and sustainability. But what exactly is modal, and why has it become such a popular choice for underwear in the U.S.?

What Is Modal?

Modal is a type of regenerated cellulose fiber made from beechwood. It’s produced through a process similar to that used for viscose, but with a more refined and controlled treatment that results in a stronger, smoother fiber. The outcome is a silky, lightweight fabric that feels natural and luxurious against the skin.

Originally developed in Japan in the 1950s, modal has gained widespread popularity in recent decades as American consumers have become more focused on comfort, performance, and eco-friendly materials.

Unmatched Softness and Everyday Comfort

One of the main reasons modal has become so popular in underwear is its incredible softness. Often described as a cross between cotton and silk, modal feels smooth and gentle against the skin—perfect for garments that are worn close to the body all day long.

The fibers have a sleek surface that reduces friction, helping to prevent irritation and chafing. Modal also moves with the body, maintaining comfort whether you’re sitting at a desk, working out, or on the go. For many, modal underwear feels like a second skin.

Breathability and Moisture Control

Modal is highly absorbent—up to 50% more than cotton—which means it wicks moisture away from the skin quickly and efficiently. This helps keep you dry and comfortable, even in warm weather or during physical activity. The fabric also dries faster than cotton, making it a practical choice for everyday wear and travel.

Because of its breathability and moisture management, modal is especially appreciated by people with sensitive skin or those who find synthetic fabrics like polyester too harsh.

Durability and Shape Retention

Despite its soft and lightweight feel, modal is surprisingly strong. It resists shrinking, fading, and pilling, even after repeated washing. That means modal underwear maintains its shape and color longer than many cotton alternatives—an important factor for both comfort and value.

Many brands blend modal with cotton or spandex to combine softness, stretch, and durability. The result is underwear that feels luxurious but is tough enough for daily wear.

A More Sustainable Option

Modal is made from wood sourced from sustainably managed forests, and its production typically requires less water than conventional cotton farming. Modern modal manufacturing processes can also recycle and reuse the chemicals involved, reducing environmental impact.

While modal is still a processed fiber, it’s considered a more eco-conscious alternative to many synthetic materials. For U.S. consumers who want to make responsible choices without sacrificing comfort, modal offers an appealing balance between performance and sustainability.

Why More People Are Choosing Modal

When you combine all its advantages—softness, breathability, durability, and environmental responsibility—it’s easy to see why modal has become a staple in underwear drawers across America. It delivers a premium feel at an accessible price point and aligns with the growing demand for sustainable, high-quality basics.

For many, modal represents the modern approach to clothing: comfortable, functional, and mindful of the planet. And it’s a trend that shows no signs of fading anytime soon.
