501® Thermodapt: Innovation for Every Season


Levi Strauss & Co.
September 9, 2025

Since 1873, Levi’s® 501® jeans have represented the spirit of innovation, authenticity and craftsmanship that sets the Levi’s® brand apart. As we continue to build on our legacy, we’re excited to introduce our newest innovation: the 501® Thermodapt.

Reimagining a timeless icon, the 501® Thermodapt introduces a new era of adaptive comfort, blending the classic fit and heritage of 100% cotton denim with cutting-edge hollow-core yarn technology to help regulate body temperature. Designed for style and comfort in every season, the innovation keeps fans comfortable all year round — without compromising the look they love.

501® Thermodapt builds on decades of heritage: the design features the iconic high rise, button fly and straight-leg silhouette, now paired with breakthrough fabric engineered for adaptive performance. The hollow-core yarn structure wicks away moisture and improves breathability in the heat, while also trapping warmth in cooler environments — creating a personal microclimate perfect for everything from late summer beach outings to cozy holiday dinners — all while staying true to the iconic look that defines the 501®.

“Innovation at its best disrupts everything else except the consumers’ experience,” said Paul Dillinger, head of Global Design Innovation at Levi’s®. “With 501® Thermodapt, we’ve gone to such great lengths to seamlessly integrate the technology into Levi’s® visual DNA, so much so that the innovation is almost invisible.”

And seamless integration it is. The 100% cotton construction of the 501® Thermodapt delivers the classic Levi’s® look and feel, but with superior softness and lasting durability. Natural fiber breathability and moisture management provide all-day comfort without worrying about the odor retention often associated with synthetics — so you can look good and feel great, no matter the forecast.

The launch of the 501® Thermodapt comes on the heels of the 501® Curve, another iteration of the timeless fit and a testament to how listening to our fans and staying ahead of trends results in continued innovation and consumer satisfaction. These recent innovations, amongst others, emphasize the Levi’s® brand’s ongoing commitment to  leading the way in denim, responding to our fans and continuously finding new ways to deliver styles that keep shoppers returning.

The 501® Thermodapt is now available on Levi.com, the Levi’s® App and select Levi’s® Stores.
