These high-quality leggings, socks, and underwear are made from recycled plastic

EnterGirlfriend Collective. This activewear brand is known for its buttery-smoothleggings(high-rise and mid-rise),sports bras, andshorts,all made from recycled plastic water bottles. (One pair ofcompressive high-rise leggings, for example, keeps 25 water bottles out of the landfill.) The company’s ethically made fabrics—along with its efforts to champion (and fund) diversity and community—have elevated the four-year-old brand into cult-favorite status.

The company also has adorable takes on athletic staples—for instance, its cropped, half-zipHummingbird windbreaker, which comes in traditional black and navy and more playful lilac and yellow. If a full-length zip-up is more your speed, theSummit track jacketcomes in the same palette. Going for a monochrome look? Either (or both) can be paired with theSummit track pantor theGazelle short. Buy the whole set, and you’ll be color-coordinated (and comfy) no matter what the season.

Last month, the Girlfriend Collective expanded its range with the launch of theEveryday GFcollection of socks and underwear. As with the brand’s leggings. these socks and underwear are made from recycled plastic bottles, which is especially important since intimates are some of the most disposable items of clothing. To take it a step further, the company is partnering with Unifi to create an upcycling program: When you’re done with your Everyday goodies, the brand will take them back and turn them into new items.

The concise, four-piece collection features two styles of underwear and two styles of socks—so you have choices without being overwhelmed by them. Socks come in quarter-length and crew-length, and in seven different colors. The soft and stretchy undies, which are laser-cut for a seamless, mold-to-your-body fit, come in a thong and brief.

While theEveryday GFcollection is available, 100% of net proceeds will be donated to organizations that support Black communities, including the Loveland Foundation, the Okra Project, and the NAACP Legal & Defense Fund—with a minimum of $20K being donated to each organization.
