Which brand is associated with active pants?

The brand that is most closely associated with active pants is Rhone. This brand specializes in providing high-performance activewear designed for men, emphasizing comfort, style, and functionality. Rhone's active pants are crafted with advanced materials that offer breathability, moisture-wicking properties, and stretch to accommodate physical activity, making them a popular choice for athletic pursuits.

Revtown mainly focuses on denim and casual wear rather than specifically specializing in active items. Reiss is known for its tailored clothing and smart casual styles, which do not primarily target the activewear market. Rhoback also offers activewear, but it does not have the same level of recognition or association specifically with the concept of active pants as Rhone does. Therefore, Rhone stands out as the strongest choice for active pants in the context of this question.
