Truepurpose Recycled Stretch-Jersey T-Shirt

We all know how tempting it is to hit snooze rather than pull on gym gear. However, as motivation goes, it doesn’t get much better than adidas by Stella McCartney’s Truepurpose T-shirt. Whipped up in a recycled polyester-blend – as part of the British designer's mission to end plastic waste – this form-fitting silhouette is short sleeves, perforated panels and crafted from a moisture-wicking fabric that keeps you sweat-free. We’re sold.

• 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.
