If you're shopping solely for eco-friendly activewear, check out Kami Activewear, which is made sustainably at every stage of the supply chain — from the material through to the packaging and manufacturing. The fabrics are made of recycled waste materials that would otherwise end up in landfill, while the orders are wrapped in biodegradable garment bags that dissolve in hot water and mailed to you in bags made from potato starch. Plus, with every purchase they donate a percentage of each sale to the Marine Conservation Society. We can wait to slip on the Kami Beluga Mesh Leggings (£85), which are currently available for pre-order.
