Impact

"A waterproof jacket hillwalking jacket that is eco-conscious too" The Ramblers Magazine

Sigma is designed with circularity in mind. It is made with a mono monomer construction. This means all components are made from the same material making the garment easier to recycle at the end of its life as it doesnt need to be broken down into separate recycling streams.

Sigma is made from 100% post consumer waste recycled polyester which itself is recyclable. Sigma's durable water repellent coating is entirely free from PFC's. Regularly wash and reproof your jacket at home to maintain its performance using Nikwax, Grangers or our own Alpkit Wash & Reproof care kits.

Do not be fearful that recycled implies a secondhand performance. Sigma has been tested for abrasion, durability, breathability and waterproofing.

Designer’s notes

"We designed Sigma with with wet weather performance, cross-over use and circularity in mind.

When it eventually comes to the end of its useful life (hopefully in many, many years’ time) most of the jacket can be recycled, rather than end up in landfill. By choosing a mono-monomer fabric construction, even down to the pocket bag mesh, we’ve made it as easy as possible to close the loop.

But we’ve not scrimped on performance to achieve this. Sigma has a 3-layer construction that’s fully waterproof and highly breathable for use in all seasons and all weathers. It’s also got all the features you need for a day on the hill like a map pocket, adjustable, wired-peak hood, semi-elasticated cuffs and soft touch fabric for next-to-skin comfort. Sigma will shrug off showers and storms alike."

Recycled materials

Sigma uses a 100% recycled polyester fabric using a single polymer meaning it can be easily recycled at end-of-life.


PFC-free DWR

Sigma has a completely PFC-free DWR treatment on its outer fabric. PFCs are potentially harmful and have been found to build up in the environment. We don't like the sound of that and are one of the first outdoor brands in the world to eliminate them from our range.

Reducing our carbon footprint

We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.

We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intensity by 15% every year to achieve genuine net zero by 2050.

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.
