Our comforters are lightweight, minimalistic and versatile in use. Thanks to their rectangular shape they can provide a perfect insulating layer: either used under a wide jacket or inside a classic sleeping bag to make it winterproof, and even under a hammock, when weather conditions drop below expectations. When needed, they can be used as a loose duvet or they can be transformed into a quilt: a hoodless sleeping bag, not insulated at the rear. Comforters are for sure one of the most universal products in our offer.

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.



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.
