The Bergen mummy sleeping bag is a sleeping bag that perfectly copies the body and thus has the best thermal insulation properties and is equipped with a retractable hood protecting the head.

The Bergen sleeping bag, like all mummy-type sleeping bags, is especially suitable for longer stays in nature. Comfort and temperature inside the sleeping bag are affected by clothing. Sleep is recommended only in underwear, or with a T-shirt. It is important to warm your sleeping bag and not heat your clothes unnecessarily.

The Bergen sleeping bag is equipped with four layers, the outer material is polyester taffeta 210T with a Rip-Stop surface treatment, thanks to which any cracks in the material do not increase further. The next layer is the inner, reminiscent of pleasant silk and is made of 210T polyester. The last layer is a double insulating layer of polyester hollow fibers (hollow fiber), where each of the two layers has a weight of 150 g / m2. The hollow fibers retain a large amount of air and ensure fast moisture removal, while having excellent insulating properties.

We choose sleeping bags mainly according to their temperature limits, where comfort means the temperature at which we will be comfortable, the limit is the temperature at which we will still be warm and last but not least there is the temperature extreme, which indicates the maximum tolerable temperature.
