KNOW WHAT YOU’RE BUYING

The table below is designed to help you understand where Montane products are made and what they are made from. Lower impact materials have a reduced environmental footprint and increased traceability via third party accreditations. For example recycled content, Responsible Down Standard certified down, and branded yarns like Tencel ™. Where a product uses a DWR you can easily see whether this uses potentially harmful chemistry (PFCs).
