Compression High-Rise Stretch-Recycled Polyester Leggings

Though a pile of empty water bottles might not usually be your first choice of workout gear, Girlfriend Collective is finding a way to make it work with these leggings. The label crushes them down into fibres through much trialling and testing before transforming them into recycled polyester – the fabric you see right here. How satisfyingly guilt-free...almost like taking the weight off your shoulders so you can focus on those barbells instead.

• 79% recycled polyester, 21% elastane

Transparency is the backbone of Girlfriend Collective, a one-stop-shop for ethically-made activewear with a pared-back, minimal aesthetic, inclusive sizing and an impressive commitment to responsibility at every level of production.
