Cropped Stretch-Knit Top

With a flexible, streamlined fit, this cropped top from adidas by Stella McCartney supports you like a second skin. The sleek design is fitted with an open back to encourage airflow when your HIIT class steps up a notch. The best bit? It’s partially woven from recycled fabric that’s been taken from beaches and coastal communities before it ends up in the ocean. Workout gear and cleaner oceans? Count us in.

• 64% modal, 27% recycled polyamide, 9% 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.
