+ unique design

+ pillow pocket

+ easily packable


The sleeping bag / insert made of a thin nanosilver thermo material serves, similarly to a sleeping bag, for you to relax, warm up and fall asleep comfortably. It is designed for universal use from sleeping in hostels and mountain huts to sleeping in extremely cold conditions.

In a hostel or in a cottage

It is often required to have your own sleeping bag under the bedding of the given accommodation facility, or you pay amounts in the order of hundreds of euros for the loan. The aim is to prevent skin contact with bedding and sheets so that cottagers do not have to wash it so often and prevent the spread of disease. At the time of COVID-19, this regulation was extended to cottages where it was not common. The insert does not need to be prepared in any special way. It has a slit on the side, which allows it to slide in comfortably. Under your head is a pocket similar to a pillow case, into which you really slide the pillow.

In extreme conditions

In the case of a mountain hike, where each deco counts, a jacket or other soft piece of clothing can be used in the pillow pocket. The insert was tested by our ambassador Vašek during the trip in the Alps (3557 m above sea level, at a temperature of 0-5 ° C) during the ascent to Dent Blanche (4357 m above sea level).

Unique design

Our inserts are printed with full-color photorealistic printing - the only one in the world. You will get a complete original. If you like neutral pieces, then you will find one-color inserts in the menu.






  • 52% polyester (Thermo ° Cool ™)
  • 44% polyester (nanosilver® antibacterial fiber)
  • 4% elastane (Lycra®)


Thermo ° Cool ™ - temperature self-regulation

The fibers are composed of hollow and channel fibers. The channels are used to remove more sweat and moisture than conventional cylindrical fiber. The sweat is drained to the outside of the fabric, from where it evaporates and the fabric dries. The hollow fibers are able to hold air, which acts as insulation. By combining these functions together, we achieve a feeling of dryness and warmth.

nanosilver® - antibacterial

Silver molecules are firmly attached to the polyester fibers. Silver is known for its antibacterial effects - it eliminates bacteria formed in sweat, which are a source of odor. Once the material dries, it does not stink. However, this process is not endless. After the first use, the odor is suppressed, after repeated use, abrasion may appear. Therefore, it is necessary to wash these materials as well. However, the abrasion intensity is incomparably lower compared to conventional materials.

Lycra® - flexibility and pliability

It gives the material greater flexibility (flexibility) and elasticity. The extensibility of these fibers reaches up to eight times the length.

Coolmax® fiber - cooling

Profiled fibers The material dries quickly and thus allows better self-regulation of temperature, which favorably supports the heart rate and thus physical performance.


The treatment of nanosilver® material does not require any special treatment. It is exactly the same as with normal functional underwear.



The nanosilver® material Himalay is very fine and light, but it is prone to mechanical damage. Be careful of velcro and sharp objects (buttons, zippers, watches) so that you do not pull on the threads.


We recommend washing at 40 ° C.


It is not necessary to iron the laundry.

Chemical treatment

Without chemical treatment

Fabric softener

We do not recommend the use of fabric softener to maintain the functionality of the nanosilver® technology. The fabric softener forms a thin film that creates a barrier between direct skin and material contact. For perfect efficiency, the silver molecules need to be in direct contact with the skin. But if it happens that you accidentally treat fabric with fabric softener, nothing happens. This film will be lost during the next wash.

Additional information:

"We warn customers about possible negative reactions and damage to the nanosilver clothing material to aggressive components of sweat, deodorants and creams before and after sunbathing. E.g. deodorants containing DEET may dissolve synthetic fibers, including PES. "
