For Fall/Winter 2026, Polartec® and ONLY & SONS bring together textile innovation and contemporary menswear in the new JASON fleece jacket, made with Polartec® Thermal Pro™.
Polartec®, a Milliken & Company brand known for its research into innovative and increasingly sustainable textile solutions, is collaborating with ONLY & SONS on the new JASON fleece jacket, designed for the Fall/Winter 2026 season. The project comes as Polartec® celebrates the 45th anniversary of fleece and combines the insulating properties of Polartec® Thermal Pro™ with the contemporary aesthetic of ONLY & SONS menswear. The result is a versatile, quality garment designed to combine contemporary design, comfort, and functionality in the everyday men’s wardrobe.

Polartec® Thermal Pro™ meets contemporary menswear
Polartec® Thermal Pro™ evolves the traditional concept of synthetic fleece with knit structures designed to balance warmth, breathability, and durability. The fabric’s construction allows it to retain heat when needed and promote heat loss during activity, offering good thermal comfort without weighing the garment down. The result is a lightweight and comfortable solution, suitable for active use.

The JASON jacket takes fleece from the outdoors to the city
The new JASON combines the softness and distinctive look of high-pile sherpa fleece with a contemporary silhouette. The result extends the tradition of Polartec® technical fabrics beyond the outdoor world, bringing it into an urban, everyday context. Subtle warmth, breathability, and versatility become the hallmarks of a garment designed to accompany you throughout the day.
Featuring Polartec® Thermal Pro™, the jacket demonstrates how technical performance and design can coexist within the same product. The diverse possibilities offered by its knit structures also represent a meeting point between textile innovation, performance research, and contemporary fashion trends.

45 Years of Polartec® Fleece Innovation
Forty-five years ago, Polartec® helped transform the outdoor apparel industry by introducing the world’s first synthetic fleece. Lighter than wool and quick-drying, the material helped set new standards for technical apparel. Today, that same legacy continues in contemporary menswear.
The JASON jacket by ONLY & SONS reimagines Polartec® fleece for a new generation of consumers, combining functionality and style. This approach reflects the evolution of contemporary clothing, which is increasingly geared toward garments that adapt to different contexts and occasions.
