REI Co-op  Swiftland Thermal Running Half-Zip - Women's

• Made with yarn that uses LanzaTech carbon-capture technology, recycled polyester/spandex blend grid fleece provides warmth, breathability and wicking at a light weight
• LanzaTech is a biochemistry company that's developed technology to capture carbon emissions from industrial sites, such as steel mills, before they enter the atmosphere
• These carbon-rich gases are then converted into ethanol, which can be used to manufacture new materials like polyester
• Wind- and water-resistant ripstop nylon panel with mechanical stretch overlays the front body and shoulders for optimal weather-blocking protection and increased core warmth
• Overlay has a durable water repellent (DWR) finish made without PFAS to help moisture bead up on the surface
