TruePurpose High-Rise Jersey Leggings

Adidas By Stella McCartney joins forces with Parley, a company that creates recycled materials using waste plastic found in the ocean, to create these black TruePurpose leggings. They're crafted from moisture-wicking recycled-fibre blend Primegreen jersey to a second-skin fit with a high-rise waist, then finished with pink reflective tape and printed logos.

• 64% recycled polyester, 36% elastane

Adidas and Stella McCartney’s longtime collaboration is a fashion favourite, with high-performance trainers, clothing and accessories that are wearable in and out of the gym. From Ultraboost sneakers to recycled track jackets, each piece is designed with function as well as form in mind.
