Synthetic Fill

Synthetic fibers are wafer-thin and particularly lightweight. They are characterized by very low moisture absorption and increased breathability. This makes them a great choice for humid areas.

Advantages & Disadvantages of Synthetic Fill

Synthetic fill is made from microfibers – chemical compounds such as polyester or polyamide. It’s a man-made product, which makes it possible to reinforce specific properties. Even when wet, it retains its thermal properties, in contrast to natural fibers such as goose down. It’s quick-drying, robust and easy to clean. However, synthetic fill doesn’t match goose down in terms of loft, comfort level and compressibility.

Material thickness

VAUDE materials meet high standards for both thread diameter (unit: denier) and thread count (unit: T = thread). You can quickly estimate how robust and heavy a material is on the basis of these two key figures. This means, for example, that for a material with the specification “40D polyamide ripstop 240T”, the thread used in the product weighs exactly 40 grams (40 denier) at a length of 9,000 m and 240 threads per square centimeter are woven in the material. The thicker the thread, the higher the denier value; the higher the number of threads processed (thread count), the more durable the material.


Sensofiber is a special microfiber that reflects your body heat while you sleep. It insulates well even when wet because it quickly transports moisture away from the body. It dries quickly, is durable, robust and easy to take care of.

PrimaLoft® insulation

We use high-quality and environmentally friendly PrimaLoft® materials for our synthetic bags to offer optimum thermal comfort.

PrimaLoft® Black Insulation Eco

PrimaLoft® Black Insulation Eco is an insulation made of fine microfibers which is characterized by a particularly high loft, excellent thermal performance and excellent compressibility. This combination of 100 % recycled material and state-of-the-art fiber technology is a powerful and environmentally friendly solution for maximum thermal comfort.



All synthetic fill VAUDE sleeping bags feature special chamber constructions that prevent the fill from shifting for reliable thermal regulation.

Single-layer Construction

Single-layer construction in synthetic sleeping bags means that the layer of lining fabric is sewn directly to the outer fabric. This type of processing, however, can result in cold spots. We therefore use this construction exclusively for our ultralight and summer sleeping bags.

Two-layer Construction

Two layers of lining are used in these bags. One layer is sewn to the outer fabric and the other to the inner fabric and the seams are staggered to avoid cold spots. Synthetic fill sleeping bags with this construction offer optimum thermal insulation.



We have made it our business to constantly reduce our own ecological footprint – to minimize resource consumption and to recycle existing materials. We therefore increasingly use recycled materials in our sleeping bags in order to conserve resources and avoid waste. You can recognize products made of recycled materials by this label on the left:

PET Recycling

For certain functional products we use material made from recycled PET plastic bottles. They are collected, cleaned and melted down. We then process the high-quality yarn that results into new products. This conserves resources and saves energy. This almost halves the impact on the environment compared to new production.

PA Recycling

Polyamides are synthetic fibers produced from crude oil. In order to conserve natural resources and recycle existing materials, we recycle post-consumer, abandoned fishing nets, which would otherwise float around in the oceans and endanger marine life. The result is new, high-quality materials. Under the name Econyl® they are used, for example, in our Green Shape Core Collection.
