Fleece is durable, warm, and lightweight. But it’s often made from unsustainable virgin polyester. Our PureActive Fleece is a warm 250gsm fabric and engineered using 100% GRS certified recycled polyester. Manufactured in renewable powered facilities from 36 (all mens, 31 for all womens) plastic water bottles, and dyed in a bluesign approved dyeing facility. All the good, and none of the bad.
