Thermal socks Lorpen TEPEX Inferno Expedit Polartec

 Lorpen TEPEX Inferno Expedit Polartec is an extra thick sock specially designed for trekking and expeditions in cold and even polar weather conditions.
These are the most advanced socks in the world with a new design that have been successfully tested at altitudes of over 8,000 metres.
T3+ technology is used - a sandwich of two layers of elastic Polartec® Power Stretch® with an inner insulating layer of Primaloft®.
Anatomical design of each sock for right and left feet.
TEPEX Inferno Expedit Polartec are very comfortable to wear and have a long service life.
Suitable for wearing with high boots.
Ideal for high-altitude climbing, hiking, trekking and hiking in extreme conditions.

Technology of thermal socks Lorpen TEPEX Inferno Expedit Polartec
T3+ - made from a combination of Polartec Power Stretch® and Primaloft® Yarn:
- Two layers of Polartec® Power Stretch in the outer layer of the socks provide warmth without adding weight. The smooth outer layer is resistant to wind and abrasion; the soft inner layer wicks moisture away from your skin for dry, warm and comfortable feet,
- The Primaloft® inner layer is made from ultra-fine polyester fibres, thinner than cashmere, for unrivalled moisture wicking and a luxuriously soft feel.

Materials
Polartec ® Power Stretch
Highly elastic material that stretches in four directions from a blend of Polyester + Spandex + Nylon. It has increased resistance to stretching and does not deform.
The unique design of the biocomposite fabric consists of two layers: a stable outer surface made of nylon, which reduces friction with other layers of clothing and increases its resistance to abrasion, is combined with a soft inner moisture-wicking layer with thermal insulation pile.
Polartec® Power Stretch® features Odor Resistant® technology, which provides antibacterial protection and prevents the formation of unpleasant odours.
The material is completely hypoallergenic.
Nylon
Nylon, or polyamide, is the world's first synthetic fibre.
Its most prominent feature is its exceptional strength, abrasion and water resistance and, as a result, high durability, 10 times that of cotton and 20 times that of wool, and it is also stronger than polyester.
In the production of socks, nylon is usually blended with other materials to give strength and elasticity.
In Lorpen socks, a nylon layer is used for extreme loads, located over the entire area, and for moderate loads - in friction zones.
The strategic placement of nylon in the outer layer of the socks guarantees a long service life.
PrimaLoft ®
A polyester yarn developed by PrimaLoft®, a world leader in the creation of artificial thermal insulation materials for high-tech clothing.
It consists of the finest hollow fibres that resemble downy threads in structure, are light, soft and compressible, and have thermal insulation parameters similar to down, which hardly change when wet. It has the highest coefficient of thermal insulation among synthetic heaters (Clo=0.92). It is soft and insulating.
PrimaLoft® is a hydrophobic fibre that repels rather than absorbs moisture. When hiking, climbing and doing any aerobic activity, your body releases sweat and heat, which leads to evaporation, but as soon as you stop, you start to freeze due to the presence of water on the surface of the body, Primaloft® fibres wick moisture away from the skin and retain body heat.
Thermolite ®
A very lightweight fibre, hollow in the centre, developed by Invista Advansa, whose main property is to retain body heat like a thermos and wick moisture away from the skin surface to the outside thanks to its water-repellent properties.
In the event of overheating during strenuous physical activity (with active sweating), Thermolite®, due to its structure, helps moisture to leave the skin surface instantly and evaporate from the surface. In this way, Thermolite® reacts quickly to overheating or hypothermia. In other words, it is a kind of "temperature controller".
Lycra ®
It is very important for socks to be able to take the anatomical shape of the foot of any size, without the formation of folds that lead to chafing on the feet.
Lycra is the best elastane yarn on the market, the material of Lorpen socks contains up to 10% stretch nylon with lycra.
The elasticity of Lorpen socks is provided by stretch nylon, with an inner elastane layer and a nylon coating.
The percentage and quality of stretch nylon determines the high elasticity and durability of the new sock.
That is why Lorpen socks retain their fit even after prolonged use and numerous washes.

About the manufacturer
Lorpen is one of the world leaders who specialize in the development and production of innovative technical socks for sports and extreme sports.
The company's motto: "Create the finest technical socks for serious applications in the fresh air."
The history of the Lorpen brand began in 1985. from a small family factory from the production of sports socks in the evening of Spain near the Pyrenees.
In 2015 Lorpen introduced its exclusive T3 technology to the market, and in 2017 it introduced Anatomical Calf Support technology.
Today's commercial efforts of the company are expanded on the European and American continents.
The company's approach to business also includes efforts to conserve as much waste as possible of Lorpen vicor fibers being removed from renewable resources.
In addition, the company is constantly working on improving environmental friendliness and reducing waste.
Extreme athletes take part in this campaign, for example, Gerlinde Kaltenbrunner is the first woman to climb all 14 eight-thousanders without supplemental oxygen.
The proven strength of the product is the fact that Lorpen hiking, sports and trekking socks are sold in more than 60 countries around the world in more than 1,200 stores.
