Panyam 450 is the most versatile sleeping bag among our products. It won’t be too warm during summer nights, but most importantly, it is perfect for the autumn months bringing the first frosty days. The Panyam series has a typical, 3-season structure: it features advanced trapezoid chambers and a collar adjusted separately around the neck to improve insulation during cold nights. The bag is slightly wider to enable sleeping with supplementary insulation, such as a liner or an additional layer of clothes, allowing experienced users to use this model in temperatures lower than suggested. Its anatomical foot box (shark fin) and 3D hood ensure your comfort. In designing, we paid considerable attention to detail, making the bag really comfortable, owing to a special no-snag zip clip, an inner pocket noctilucent zip puller and a hood with cords of different textures to facilitate adjustment in darkness. Panyam 450 is the dream lightweight sleeping bag for autumn trekking tours or quick spring excursions high in the mountains.

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.



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.
