What does the acronym 'ABC' stand for in Lululemon's ABC pants?

In Lululemon's ABC pants, “ABC” stands for Anti Ball Crushing.

The deliberately cheeky name describes the engineering goal of the trousers: giving the wearer more room and comfort through the crotch. Lululemon achieves this with an ergonomic gusset that reduces tension in the front rise, allowing easier movement while sitting, walking, commuting or exercising.

ABC pants were created as part of Lululemon's expansion from women's yoga apparel into men's clothing. The company introduced the ABC concept as a functional alternative to restrictive traditional trousers, combining a jeans-like or office-casual appearance with stretchy technical fabrics such as Warpstreme.

The phrase is sometimes softened in casual discussion, and product descriptions may emphasize “ABC technology” rather than spelling out the words. That can lead readers to invent alternatives such as Athletic Body Control or All Day Comfort. Those phrases describe plausible apparel benefits, but they are not the original expansion of the acronym.
