Patizon D290 Ultralight Down Sleeping Bag

The Patizon D290 is a masterclass in ultralight performance, engineered for those who demand uncompromising quality in the mountains. Designed and crafted in Europe, it delivers an exceptional balance of warmth, weight, and packability—refined to the smallest detail for fast-moving adventures.

Filled with premium 700+ cuin European duck down in a precise 90/10 ratio, the D290 offers outstanding thermal efficiency while remaining remarkably lightweight. With a comfort rating of around 3°C, it is perfectly suited to summer trekking, alpine bivouacs, and multi-day expeditions where every gram matters.

The advanced Z-shaped baffle construction minimises cold spots and maximises heat retention, while the use of high-performance fabrics such as Pertex Quantum and Toray Airtastic ensures durability, breathability, and resistance to moisture.

Every detail is considered. The innovative straight front zip enhances thermal efficiency and reduces packed volume, while the anatomically shaped design, insulated hood, and precision fit create a cocoon of warmth without excess bulk.

Packing down to an impressively compact size, the D290 disappears into your rucksack—yet delivers reliable performance when temperatures drop. It is this refined balance of minimalism and performance that defines truly premium outdoor gear.
