Optimal thermal protection under the hammock

Thanks to the ingenious adjustment system, the Biopod DownWool Hybrid Underquilt adapts to almost all hammock lengths and can be attached with ease.

To prevent unintentional shifting of the Underquilt, there are adjustment hooks on the sides that are attached to the hammock. An elaborate oval chamber system prevents the DownWool filling from slipping.

In the areas that need increased insulation, the proven DownWool insulation has been used. The unique DownWool filling made of high-quality, RDS-certified down and wool ensures an excellent sleeping climate. The outer sections, which usually tend to condense, are filled with moisture-insensitive Synthdown.

The underquilt has two warmth levels: In cool temperatures, turn the windproof, seamless side out. If it gets warmer, the windproof side can be turned inwards towards the hammock, thus reducing the insulation.

The unique Feature of our DownWool products is their innovative insulation: DownWool is a natural insulation made of 70% down and 30% wool and combines the advantages of both natural materials. Very good insulation and a pleasant feel-good climate.


The natural high-end DownWool-Insulation is a blend of 70% high-quality RDS-certified down, which provides high insulation, and 30% wool from the Alpine region, which acts like a lightweight natural air conditioner. The combination is perfect. Nothing insulates as well as high-quality down. The 30% wool content absorbs any moisture that arises and thus keeps the down naturally drier. Down has a very high insulating capacity at a low weight. However, down only insulates as long as it is dry and fluffy. With increasing humidity, the fine branching of the down collapses, which considerably reduces the insulating effect of the down. For this reason, the down is often treated with water-repellent agents. With DownWool, this is made unnecessary by adding the wool content. Wool can absorb up to 30% of its own weight in moisture without losing its insulating effect. Furthermore, wool is very temperature regulating and creates a pleasant microclimate in a natural way.

The result is a unique sleeping climate, which means that the temperature range in which you feel comfortable and sleep well in a DownWool products is particularly wide. This makes DownWool products popular all-rounders.
