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).

Bottle to Base Layer

Did you know this base layer is made using recycled plastic bottles? Not only does it reduce our reliance on finite, unsustainable resources, we’re able to help reduce global plastic waste. Another major benefit of polyester is its ability to not absorb water and other oils - this means it dries quickly and doesn’t stain easily win-win!
