A sleeping bag is for sleeping, so the quality of sleep in the sleeping bag is crucial.

These days, sleeping bags are becoming increasingly narrower and shorter to be considered the lightest on the market. But does that really make sense?

We conducted tests in our sleep lab and found that a sleeping bag needs a certain length and, above all, width . When sleeping, people often place one leg to the side to relieve pressure on their hips. If this isn't possible, their body won't find a comfortable sleeping position. This applies to both back and side sleepers.

In addition, the sleeping climate in your sleeping bag plays a major role. If it's too warm, you'll sleep just as poorly as if it's too cold.

To achieve a more balanced sleeping environment, natural materials are crucial – and the best material for this is wool. Wool acts as a natural air conditioner, significantly expanding the temperature range in which you feel comfortable. The right amount of wool is important, as every sleeping bag needs the optimal amount to ensure a balanced sleeping environment.

Better sleep leads to better fitness the next morning.
