Like many of the leggings on this list, the SOS Activewear Vaquita Power Leggings (£95) are also made out of Econyl (72 percent Econyl, 28 percent elastane to be exact). The London-based activewear brand is relatively new to the fitness gear game (it officially launched in February 2020), but these high-waisted leggings (which are all handmade) are already getting rave reviews from customers who are loving the quality, versatility, and flattering design. They're so comfortable, in fact, they're great for lounging around the house, too.
When it comes to being eco-friendly, the brand also goes beyond just using sustainable fabrics. SOS Activewear uses recycled packaging and carbon-neutral shipping when sending out all of its orders.
