Cotton / CICLO® Recycled Nylon / SilkSoft knit with a cool-touch hand feel. This double knit features silk for maximum softness, and the cotton is blended with CICLO® fibres — a recycled polyester developed to biodegrade at a similar rate to natural fibres. This means less microplastics in our ocean, so it's good for you and our planet. Wear now (and for years to come) and have a lighter impact later. Go you!
