Adult Sleeping Bags

Of course! On decathlon.com.gr you will find a very large selection of adult sleeping bags for every need: from spacious, rectangular sleeping bags that offer comfort just like your duvet at home for summer getaways, to technical sleeping bags that provide maximum warmth and minimal weight for overnight mountain stays.

The choice is primarily based on three factors: ambient temperature, method of transportation, and shape. If you are going by car to an organized campsite in the summer, a comfortable, rectangular sleeping bag is ideal. However, if you are wild camping or backpacking and carrying everything on your back, you need a mummy-shaped sleeping bag that hugs the body to eliminate air pockets, while folding down to a very small volume and weighing minimal amounts so it fits easily into your pack.

Every Decathlon sleeping bag is tested in independent laboratories according to the European ISO 23537-1 standard and displays two main temperatures:
Comfort Temperature: This is the lowest temperature at which a person, in a relaxed body posture, feels completely comfortable and warm without feeling cold. You should always base your purchase on this temperature.
Limit Temperature: This is the temperature at which a person, curled up in a fetal position to limit heat loss, is in thermal equilibrium (not feeling cold, but not warm either).

The difference lies in thermal insulation, weight, and moisture resistance. Down sleeping bags offer the ultimate warmth-to-weight ratio. They are incredibly lightweight and compress into an exceptionally small volume, but they are more expensive and lose their insulating capacity if they get wet.
Synthetic filling sleeping bags are more economical, very easy to clean, and their main advantage is that they continue to keep you warm even if they absorb moisture or sweat, making them ideal for coastal humidity.

To help the sleeping bag retain its loft and insulating capability, follow these steps:
Machine wash it on a gentle delicate cycle (30°C) with all zippers closed, using a minimal amount of liquid detergent (no fabric softener). If it is a down bag, a smart trick is to place 2-3 tennis balls in the drum to keep the down from clumping.
Let it dry completely flat in a shaded, well-ventilated area.
The golden rule for storage at home is never to store it tightly compressed inside its small compression sack, as this will destroy the filling. Instead, hang it on a coat hanger or store it loosely inside a large mesh or cotton bag.

A sleeping bag is suitable for winter camping only if its stated "Comfort Temperature" matches the winter conditions of the area you will visit (e.g., 0°C, -5°C, or lower). Summer sleeping bags (comfort at 15°C or 20°C) are completely unsuitable for winter and can become dangerous by leading to hypothermia. For your winter expeditions, choose the technical Forclaz Trek models designed for low temperatures, and don't forget to always use a high-quality sleeping pad, as insulation from the frozen ground is just as important as the sleeping bag itself!
