In the year since Girlfriend Collective launched their full collection of sustainable athletic wear, the cult-favorite brand has amassed a following of loyal customers and rave reviews. And it’s easy to see why — the leggings and bras are flattering and comfortable but also stand up to strenuous workouts. But what really sets Girlfriend Collective apart from its competitors is its innovative manufacturing process that uses recycled water bottles to create the fabric. The brand didn’t want to just stop there and started looking into other materials that could be recycled into affordable, luxe activewear. Their newest Cupro Collection uses waste produced by cotton manufacturing to create a tee that you can truly feel good about wearing.

The Cupro Collection has five styles of drapey, breathable tops that retail for $28-$38 and come in a range of pleasing, minimal hues that are the label’s signature. There’s Jane, a cropped tee; Frances, a scoop neck tee; Celia, a classic tank; Stella, a high-necked tank and Margot, a ballet-inspired wrap top. Girlfriend Collective will be debuting these styles one at a time over the next couple of weeks.

As with previous collections, Girlfriend Collective is transparent about their manufacturing processes. The cupro material comes from a Japanese facility that recycles all waste produced by the plant and achieves a near 100 percent recycling rate. While the cupro t-shirt already requires far fewer gallons of water to make than a traditional cotton tee, Girlfriend Collective is going the extra mile and will donate 10 percent of net proceeds to Charity Water to offset the cost of producing the collection.
