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 durable water repellent DWR that's completely free from PFCs. 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.

If one of our products doesn't meet your expectations upon delivery, or if during its lifetime it doesn't live up to the demands placed on it, please return it to us for repair, replacement or refund. Find out more about ourAlpine Bond.

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 Initiativewhich 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.

End of life
