Girlfriend Collective

Sustainability meets style with Girlfriend Collective, an active and loungewear brand that makes all their pieces with 100% post-consumer water bottles (you can even read the breakdown of how many bottles went into your order). Dress from top to toe with workout basics like shorts, leggings, bras, and comfy undies and socks, all in sizes XXS to 6XL. Once you're done with the clothing, you can give it another life by sending it back to the brand to be recycled again.

If you're a fan of the monochrome outfit, then SET ACTIVE is the shop for you. The brand features an array of simple but stylish basics available in their Core Collection colors, a line of tastefully muted tones that changes from year to year. Get your sweat on in a classic legging and crop top set in popular shades like Espresso or Slate, then lounge around afterward in sweats and a comfy one-shoulder sports bra in Bloom or Baby. Not into monochrome? Mix-and-match the signature shades to keep them colorful.

Size-inclusive brand Summersalt is a one-stop shop for your sustainable summer fashion, with athletic wear, swimsuits, lounge and sleepwear, and everyday clothes available in sizes 2 to 22, made with recycled plastics or natural materials. Choose from staples like high-rise leggings, bike shorts, and sports bra tanks for your gym session, or cozy up in terry joggers, sweat shorts, or fleece sweatshirts if you're going for more of an athleisure vibe. Similarly, colors and styles run the gamut from monochromatic jewel tones to flashier patterns like leopard or floral prints.
