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).

Whether ski touring in the Alps, or taking on an extreme mountain expedition - these thermal leggings will deliver essential warmth on a wide range of cold adventures.

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!

    Warm, comfy, great value

    Now a regular Montane customer for the guaranteed high quality kit. These long Johns were no exception. Super warm and comfy, stretchy, I forgot I was wearing them on the first cold snap of the winter - looking forward to adding them to my exped kit for winter days to come!
