All Cumulus® products are proudly crafted in Poland, allowing us to maintain the highest quality standards while minimizing our carbon footprint. Responsible production is at the core of everything we do. For us, sustainability also means ensuring fair working conditions.

By choosing our products, you’re giving back! We donate 1% of our sales to organizations like the European Outdoor Conservation Association, which leads initiatives to protect biodiversity and preserve natural habitats, and the Wetland Conservation Center, dedicated to safeguarding swamps and restoring drained wetlands to their natural state.

Down

 

Years of breeding experience, a specific climate and research facilities are the secrets behind the excellent parameters of Polish down, which is considered to be the best in the world. Despite technological advancement and attempts to make artificial insulation that would be just as reliable, down still remains unrivaled.

Ethical sourcing

 

We only use down from certified Polish producers. Thanks to their geographical proximity, we can monitor the production. We are absolutely sure down used by Cumulus has been ethically sourced. It is from free-range geese that have access to water. The excellent breeding conditions are also reflected in the down’s high quality.

Fabrics

 

Pertex® and Toray®, two fabrics we commonly use in our products, are made in Japan. Renowned in the outdoor world, they are both high-performers and have an impressive resilience considering their lightweight structure. At 19g/m2 Toray Airtastic® is the lightest downproof fabric in the world.

Zips

 

YKK® is the most trustworthy zip producer in the world, whose zips highly outperform the competition. Almost all our products feature YKK® zip - from clothing, accessories, to sleeping bags.
