Toray Airtastic™ with a weight of 19 g/m2 – is one of the lightest downproof fabrics available on the market. Despite its low weight, the fabric is resistant to tears and abrasions. The material is siliconized and coated with a DWR layer, which gives it hydrophobic properties. It feels like silk to the touch, does not rustle, and is pleasant on the skin.

Filling: highest quality Polish down with a loftiness ratio of 850 cuin, 98/2.

Fill weight: 700g (size L).


The ULTRALIGHT 700 III sleeping bag features a minimalist design, anatomical mummy shape, advanced hood design, generous foot box and V-shaped down chambers.

ULTRALIGHT 700 is designed to minimize weight and provide thermal comfort during the period from autumn to spring when temperatures drop to -5°C. The sleeping bag is made of super lightweight Airtastic® 7D material from the Japanese company Toray®. Despite its low weight, the fabric is durable, downproof, and pleasant to the touch. The sleeping bag is filled with 700g of 850 cuin loft down in a 98/2 ratio (down/feathers), ensuring warmth during freezing nights. During the design process, weight was a crucial factor, so an anatomical shape was used, tapering the sleeping bag where possible. A specially designed spacious foot box was created at the foot area to provide room for our feet and improve thermal efficiency. At the knee and hip areas, a special construction extension was included to enhance ergonomics. The hood is shaped to fit our head, reducing the overall weight. Double-stripped zippers are placed to prevent fabric from getting caught. Moreover, generous down-filled strips ensure effective insulation along the zipper. The hood and spacious thermal collar can be adjusted using elastic hidden in special internal tunnels, allowing for a snug fit without discomfort. The sleeping bag is constructed with 58 spatial V-shaped down chambers (DSV). V-shaped chambers ensure optimal distribution of down and guarantee even distribution. This design does not significantly impact the weight while eliminating thermal bridges.
