Designer‘s notes

"We designed the Sigma with circularity in mind, so that when it eventually comes to the end of it’s useful life (hopefully in many, many year’s time) the majority of the jacket could be recycled, rather than end up in landfill. By choosing a mono-monomer (try saying that fast!) fabric construction, even down to the pocket bag mesh, we’ve made it as easy as possible to close the loop. Some elements like the zips and cord aren’t yet recyclable, which is where the challenge for future development lies. No one said it was easy…"

Impact and Product Care

Caring for your DWR

To keep your jacket’s DWR treatment in good condition, wash it regularly in pure soap or a specialist cleaner. You may also need to refresh the treatment once or twice a year dependent on usage. Use a spray-on reproofer to maintain your jacket's wicking ability.

We have dedicated Repair Stations in our stores and we're fully equipped to breathe new life into your old kit. This includes spare parts, patches, new zips and wash and reproofing of your down and waterproofs. Pop into any store or contact us online for more info.
