The system consists of a warm winter sleeping bag and a waterproof cover (bivy) that protects against rain, snow, dirt and wind, the elements of the system can be used together or separately depending on weather conditions.
The increased internal space of the system allows you to sleep comfortably even with full ammunition. The zipper is unzipped to the bottom, which makes it easy to enter and exit the system, and if it gets too warm, you can open the bottom part or open the sleeping bag completely and cover yourself with it like a blanket.
Special loops and buttons connect the sleeping bag and protective cover into a single system. This way, the bivy and the sleeping bag do not twist, and the interlocking sliders allow you to close and open the system in one motion.
Thanks to its anatomical shape and modern Termoloft insulation, the sleeping bag effectively retains heat down to -15 °C (you can sleep in clothes at lower temperatures).
Termolof is a synthetic insulation made of ultra-fine hollow fibres made in Ukraine, which has high thermal insulation performance, good compressibility and quick recovery.
Thanks to the 10,000 mm waterproof fabric and glued seams, the bivy provides reliable protection against precipitation and dirt.
The material is a thin and durable nylon with hydrophobic impregnation, resistant to fluff, fibres and wind, its stability and abrasion resistance are achieved thanks to the thin Micro Rip-stop structure.

Recommendations for use
- The sleeping bag is designed to be used with a sleeping pad - a camping mat that insulates the body from the cold ground.
- Fold the sleeping bag into the transport bag randomly each time - this will prevent the insulation from falling off and extend its service life.
- It is recommended that you wash your sleeping bag as little as possible, following the manufacturer's recommendations and using appropriate detergents, and using a liner will help you wash your sleeping bag less often.
- It is recommended to dry the sleeping bag whenever possible in the field, and be sure to dry and ventilate it well before storing it for a long time.
- Store the sleeping bag in the most fluffy, non-compressed state - this will extend the service life of the insulation, and it is even better to store the sleeping bag in a special mesh bag.
