Materials

nanosilver® yarn

All nanosilver® textile products are made of yarns which are enriched with silver molecules and are securely fastened to the fibre. The molecules of silver don’t emit into the environment therefore our products are environmentally friendly and don’t harm human health.

Nanosilver® yarns are in the production combined with other functional materials – COOLMAX®, COOLMAX® All Season, Thermo°Cool™, Lycra and Bio Cotton. Individual products are labelled accordingly to their material structure, on the website and on related material tags.

Different combinations of materials are intended for different uses. Thanks to silver molecules all products acquire antibacterial properties.

Knits

Antibacterial properties of molecules of silver, that are bonded to the yarn, are making nanosilver® clothes befitting to be worn as the first layer - directly on your body. These yarns are designed to allow continuous use without any foul odours.

Materials

  • - act as a prevention against fungi and bacteria
  • - do not cause allergic reactions
  • - antimicrobial property of the materials works for the whole service life of our products
  • - have the absorption capacity, breathability and elasticity
  • - shape and design guarantee long wearing comfort

Classic material

  • 60% cotton
  • 32% polyester (antibacterial nanosilver® fibre)
  • 8% elastane (Lycra®)

BIO cotton – freshness, breathability and organic origin
This material is firm even when pulled and resistive against galling. This durability increases by approximately 20% when the material is wet. It is suitable for the products which are strained and must be washed very often. The products are pleasant to touch and are able to absorb large amount of moisture, e.g. sweat.
Organic cotton is grown without the use of any synthetic agricultural chemicals such as pesticides or fertilizers. It is softer to touch because its fibres are intact with any chemical which are normally used during growing and processing of cotton. You will not find any chemical odours in our products because formaldehyde is not used during the processing. It is more sensitive to skin and it is suitable for allergic people. It doesn´t contain any chemicals and it is more breathable.

nanosilver® - antibacterial
Silver molecules are bonded onto the polyester fibre. Silver is well-known for its antibacterial properties – it can eliminate bacteria which are in sweat and are the odour-producers. As soon as products dry, they do not smell. Our products can be continuously worn for several days without washing because our products suppress foul odours. However, this process can´t be repeated forever and it is desirable to wash these products when needed. Our products are save to wash in a way it is stated on the label.

Lycra® - elasticity and pliability
Lycra® improves the elasticity of materials. These fibres can be extended up to eight times its length.

Classic clothing material is a cardinal line of nanosilver® clothing for universal use. It is popular for comfortable cotton touch, flexibility and colour fastness. It is suitable for everyday wear as well as for training load.

Classic products

- treated just like regular clothes (recommended to wash at 40° C) no need for ironing (if ironing is needed then iron only on low heat)

All Classic products

Dakar material

  • 52% polyester (COOLMAX®)
  • 48% polyester (antibacterial fiber nanosilver®)

COOLMAX® fibre - cooling
Profiled fibres drain moisture and sweat to larger surface of the material therefore the moisture evaporates fast. Products dry more quickly and are able to make better thermal exchange which is perfect to support pulse and improves physical exercise.

Clothing made of Dakar material is suitable for sports and casual wear from warm to extremely hot days. For quick ventilation and cooling of the body we have added COOLMAX® fiber. These products were tested by riders on the rally-raid Dakar.

Thermal Himalayas Material

  • 52% polyester (COOLMAX® All Season)
  • 44% polyester (antibacterial fibre nanosilver®)
  • 4% elastane (Lycra®)

COOLMAX® All Season - thermo autoregulation
The fibres are composed from hollow and channel fibres. These channels are used to drain sweat and moisture away more efficiently than with common cylindrical fibre. The sweat is drained away onto polyester fibre surface from where it evaporates and the clothes can dry fast. The hollow fibre is able to hold the air within and it works as an isolation. Connecting these two functions we can reach dry and warm feeling.

Lycra® - elasticity and pliability
Lycra® improves the elasticity of materials. These fibres can be extended up to eight times its length.

Clothing made of Himalayas material is a line of thermal nanosilver® clothing for cold or freezing conditions and for moderate to extreme physical exercise. Thermo°Cool™ keeps the body warm and dry thanks to channel fibres, which remove a high amount of perspiration from the body onto the fabric surface and the next layer where it evaporates.

This material has been tested in the Himalayas — to Cho Oyu and Lhotse at altitudes above 8000 MASL.

ACTIVE material

  • 90% Polyester Coolmax® ALL SEASON Fresh
  • 10% elastane (Lycra)

Silver molecules are firmly attached to the polyester fibers. Silver is known for its antibacterial effects - eliminates bacteria from sweat which is 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 using the smell may appears again. Therefore, it is necessary to wash these materials as well. However, the odor 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.

Key Components of Our Materials: The Foundation of silver nanoparticle textiles and merino clothing

Our materials use carefully selected components that ensure their unique properties and functionality. Thanks to them, our silver socks, nanosilver socks, and merino wool socks have earned the trust of our customers.

  • nanosilver® Yarn: The foundation of all our textile products. It is enriched with silver molecules firmly attached to the fiber, ensuring strong antibacterial effects and odor elimination. The silver does not release into the environment nor harm the human body.
  • Organic Cotton: Grown without pesticides and chemical fertilizers. It feels softer, is more skin-friendly, and more breathable because its fibers are not damaged by chemicals. It smells cleaner because no formaldehyde is used during processing.
  • Coolmax® (and Coolmax® All Season): A profiled and hollow fiber that efficiently wicks moisture and sweat to a larger fabric surface, where it evaporates faster. It provides temperature autoregulation, keeping you dry and cool in heat and warm in winter. Ideal for anti-sweat socks.
  • Merino Wool: Silky-soft sheep wool with high insulating and absorbing abilities. It keeps warm even when wet and is unsuitable for bacterial growth. Perfect for women’s merino clothing and men’s merino T-shirts.
  • Lycra® (Elastane): Provides the material with exceptional elasticity and flexibility, with stretchability up to eight times its length. Ensures excellent body fit and freedom of movement.
  • Polyester Microfiber: Adds a very pleasant touch and warmth to the material.
