Selva 450 is a light and user-friendly, , 3-season hammock down underquilt designed to elevate your outdoor sleeping experience. Crafted with meticulous attention to detail, this underquilt combines exceptional warmth and compactness to keep you comfortable during chilly nights.

Its full-length and three-dimensional structure, adapted to the shape of a hanging hammock ensure efficient insulation without compromising on weight. Constructed using Pertex® Quantum fabric, renowned for its light properties, with premium 850 FP goose down filling, Selva 450 will surprise you with its warmth-to-weight ratio. When it's time to pack up, you'll be amazed at how compactly the underquilt compresses. Optimal warmth distribution is guaranteed both by carefully selected materials and efficient construction. Horizontal “H” type chamber design keeps the down from shifting under gravity, and differential cut prevents down compression caused by the tension of the outer material. The intuitive suspension system, equipped with elastic cords, offers remarkable adjustability, allowing you to fine-tune the underquilt to minimize drafts and ensure a secure fit.

Selva 450 pairs perfectly with our Taiga 360 topquilt and Mugga hammock. Together, they create a winter set that guarantees exceptional comfort even at temperatures hovering below 0 degrees. The understated color scheme seamlessly blends with nature, allowing you to immerse yourself in the surroundings. Selva 450 is a must-try both for newbies just getting started and for conscious gear enthusiasts seeking the ultimate lightweight setup to enjoy hammock adventures.

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.
