Sigma waterproof jacket - TGO's Best in Test

Sigma is our 3-layer waterproof designed to keep you dry and protected when the weather has a tantrum and throws its worst at you: wind, rain, sleet and snow.

It's no surprise then that it's just been awarded Best in Test by The Great Outdoors in their latest hardshell jackets review - as well as being given their Greener Choice Badge thanks to its 100% recycled and recyclable fabric and PFC-free DWR.

How our design team make it better

We innovate our fabrics with the world's best mills to ensure we stay at the forefront of performance and sustainability. This results in the Sigma boasting a 15,000 HH waterproof rating and 10,000 MVTR breathability rating, making it best in class for outdoor activity in the UK's temperate climates.

Designed with circularity in mind from the beginning using recycled and recyclable materials and water-repellent treatments free from harmful PFCs to ensure impact is kept to a minimum across the entire product lifespan.

Shop Sigma. The waterproof made better.
