Which of the following brands offers a range of active tops?

Ibex is recognized for its commitment to activewear and offers a variety of active tops designed specifically for outdoor and athletic activities. The brand focuses on performance materials that provide comfort, breathability, and moisture-wicking properties, making them ideal for sports and other physical pursuits. This aligns well with the characteristics sought after in active tops, such as durability and fit.

In contrast, Imogene + Willie primarily specializes in high-quality denim and casual wear rather than active apparel. Iron Heart is known for its heavy-duty motorcycle clothing and denim, which do not typically include a focus on active tops. J. Press offers traditional menswear with an emphasis on classic styles and does not venture into the activewear category. Thus, Ibex stands out as the brand that aligns with the criteria of providing a range of active tops.
