The People Tree Yoga Pocket Leggings (£39) aren't made from recycled nylon but rather 95 percent GOTS (Global Organic Textile Standard) and Fair Trade certified organic cotton, blended with 5 percent elastane to add stretch and ensure they can be worn for a wide variety of activities. Available in burgundy and basic black, they're also great option for lounging around the house thanks to the comfortable and breathable fabric.
