More info

CUMULUS Selva 450 - is 3-season full-length underquilt providing efficient insulation over the entire width and length of the hammock. 
Made of Pertex Quantum fabric which is breathable, lightweight and durable. Filled with 850 cuin of ethically sourced Polish goose down.

Its shape (narrowed towards the bottom) fits the shape of the hammock perfectly and thanks to the differential cut the down filling is not compressed but can expand under the sleeping person in order to prevent cold spots. On the both ends of the underquilt you have got draft collars which prevent the cold air from getting inside.

Selva underquilts were designed to be as intuitive and easy to setup as possible. To create a whole hammock set you will need the Selva 450 Underquilt and a Taiga 360 topquilt.

DOWN FILL: 850 FP Polish goose down, ethically sourced

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.

Cumulus down


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.

Cumulus ethically sourced down


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.
