DEFINITION of 'Athleisure'

A fashion trend characterized by athletic clothing that is both comfortable and esthetically appealing. This trend grew out of the dynamic use of the 'yoga pant.' Though yoga pants were designed for the gym, their comfort and simple look led women to start wearing them in a variety of casual and formal settings. Initially popularized by women, athleisure has branched into men's clothing as well. Additions to the athleisure line-up include: leggings, tights, sweat pants, hoodies and varsity jackets.

BREAKING DOWN 'Athleisure'

Lululemon Athletica Inc. (LULU) is the brand that started the trend, but it didn't stop there. Other early adopters of athleisure include Nike Inc. (NKE) and American Apparel Inc. (APP). Athleisure as a market continues to grow, replacing traditional activewear and even cutting into jeans sales. Companies like Levi Strauss & Co. and Kate Spade & Company (KATE) are rushing to release products to fit the market. As with any product trend, companies are struggling not to be left behind, and investors can capitalize on this opportunity.
