The warmest Cumulus® down jacket, designed for outdoor activities in the toughest winter conditions. The technical cut and solid, yet light construction will provide you with full comfort during winter bivouacs or ridge stops in low temperatures.

Thermal insulation is guaranteed by a thick layer of 255 g of Polish goose down with an outstanding 850 FP. Its impressive properties have been additionally enhanced by hydrophobic treatment, which makes the down resistant to moisture. The outer Pertex® Quantum Pro 29 g / m2 fabric with a water-resistant membrane and no "through" stitching, thanks to the use of H-chambers, will protect you against heat loss, especially in severe frosts. A bit more spacious than the standard cut, allows you to put an extra layer of clothing under the jacket, and you will easily fit a climbing helmet under the hood. The cuffs and waistband are adjustable and provide exceptional protection against strong wind.

Neolite Endurance down jacket will keep you safe and warm during longer stopovers. Throw it on for full freedom of movement and protection against the cold even in the most demanding weather conditions.

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.
