"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.
The materials used in construction were the same but the coverage was not, resulting in increased sheerness. We want you to Down Dog and Crow with confidence and we felt these pants didn't measure up."
Lululemon added in a statement that the recall would affect 17 percent of the women's pants it sells.
The Wall Street Journal reported Monday that the recall would have a serious impact on the company's bottom line. Shares fell 4.8 percent after Lululemon announced that the yoga pants recall would bring its first-quarter sales down from an expected $350-355 million to $333-343 million.
