Hagger, the American menswear label that coined the word ‘slacks’ back in 1934, is the latest to join the growing trend of using fabrics spun from post-consumer plastic waste.

The design house has announced that over 80 million post-consumer plastic bottles have been recycled and woven into its latest line of eco-friendly men’s trousers.

The LK Life Khaki trousers, which are part Hagger’s E-CLO label, comprise a unique blend of cotton and ‘Repreve’ spun from recycled materials, including post-consumer plastic bottles. Each pair of trousers contains the equivalent of seven recycled plastic bottles.

“Since it’s founding in 1926, Haggar has led the menswear industry in innovation by successfully merging style, quality, and craftsmanship with performance and functionality,” says Michael Stitt, CEO of Haggar Clothing Co. “With the use of REPREVE in our E-CLO and LK Life Khaki apparel, we are proud to incorporate sustainability into our product offering.”

The E-CLO and LK Life Khaki lines are available in more than 2,200 locations in the U.S., Canada and Mexico, including Macy’s, JCPenney, Kohl’s, Belk, Boscov’s and other leading department stores, as well as online at Haggar.com.
