Expert quality


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.

Hydrophobic down

When in contact with water, down quickly loses its fill power and insulating properties. Hydrophobic down has a highly increased water resilience. Much more time is needed for it to lose loft and even when moist, it dries relatively quickly. The hydrophobic down used by Cumulus is PFC free.


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.


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.
