The Luon pants, made from a combination of nylon and Lycra fibers, are one of the retailer's product staples and account for about 17 percent of all women's pants in its stores.
The hubbub comes a week after Lululemon said it was recalling its black "Luon" yoga pants, which account for about 17 percent of all women's pants in its stores, because their material was too sheer.
"The ingredients, weight and longevity qualities of the pants remain the same but the coverage does not, resulting in a level of sheerness in some of our women's black Luon bottoms that falls short of our very high standards, " Lululemon said in a release.
