The year-round sleeping bag ZFISH Hardcore Sleeping Bag 5 Season will keep you warm even in the most extreme conditions. It has hollow fiber padding and a removable middle layer. Thanks to the removable middle layer, it is incredibly versatile and can be used even in the warm summer months. The upper inner part around the head and body is made of microfleece, which is immediately warm to the touch, the lower part of the inside of the bag is made of a smooth fabric that prevents possible catching on the legs. The generous cut allows comfortable covering of the entire shoulders and does not allow warm air to escape. Another nice feature is the oval cut of all the individual layers, which allows you to practically completely fit into the sleeping bag and keep warm in truly extreme conditions. Of course, there are high-quality zippers with an overlap due to heat leaks.
