TruePurpose Stretch-Woven Jacket

A longstanding collaboration, the adidas by Stella McCartney line combines both spec and style. Proof? The TruePurpose jacket. Crafted from environmentally friendly recycled polyester that's imbued with a hefty hint of comfortable stretch, this zip-through layer keeps both warmth and breathability in mind; while laser-cut ventiliation keeps air circulating, the moisture-wicking Aeroready technology keeps you dry (and, more importantly, comfy).

• 79% recycled polyester, 21% 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.
