COOLMAX® is a polyester yarn from Invista® with channels to efficiently transport moisture away from the skin to the outside of the sock.


Very lightweight polyester with hollow core developed by Invista, whose key hydrophobic property retains body heat and expels moisture away from the skin.


This is a polypropylene fiber whose main property is that it dries quickly while offering a good, warm feeling and comfort.


Polyester yarn developed by Primaloft® that combines 30% Primaloft® fibres with 70% recycled post-consumer polyester. The result is a soft, thermal insulated hydrophobic fiber.


Polartec Power Dry® was created to give base fabrics greater efficiency and faster dry times. By designing mechanical wicking fabric with our patented bi-component construction we invented a superior base material that pulls moisture from the skin, expands for faster evaporation and lasts the life of the fabric.


Polartec Power Stretch® was developed to expand our base fabric’s durability and range of motion. By utilizing elastic fibers with enhanced resilience in Polartec® stretch construction we made a performance-fit base fabric that can handle the pressure of demanding physical activities.


Polartec Alpha®  is a new technology with active insulation that regulates core body temperatures during both dynamic and static activities. This latest advancement in adaptable breathability helps eliminate the need of shedding or adding layers while on the move.


Nylon yarn that incorporates a special natural mineral inside that converts the thermo-energy generated by the body during activity in far infrared rays that are returned to the skin. Scientifically proven to boost energy level and strengthen performance during all sport activities.


This polypropylene fibre contains an antibacterial additive in the core. Its main property is that it is extremely fast-drying giving warmth and comfort.


Nylon is a synthetic continuous fibre that is characterized by its resistance and capacity to cushion. This is the fibre that best holds up against wear and tear. Its strategic placement in the exterior layer of a Lorpen sock guarantees a long life.


LYCRA® is a synthetic elastane fiber that can stretch up to six times its length and return to its original state – time and again. LYCRA® fibers have redefined comfort, fit, freedom of movement and shape retention in virtually every garment category since its first use as a substitute for rubber over 50 years ago.



Tencel® is a cellulose Lenzing fiber which comes from Eucalyptus plants on certified sustainable plantations. Tencel®’s nano-structure provides exceptional wicking, accumulation, expansion and drying of moisture.


Merino Wool is a finely crimped and soft wool with staples that are commonly 65 – 100 mm long. The core of a merino fibre is hydrophilic (water retaining), and is breathable. The fine micron diameter ensures it feels soft and comfortable next to the skin.


The new “MerinoDry” yarn complements the main benefits of the superfine Merino wool (softness, natural warmth, anti-odor…) with a synthetic fiber that improves the moisture management properties in the sock, thanks to lower humidity absorption and to a faster drying rate.


This is an intimate mix of merino and acrylic that results in a very pleasant to touch yarn that improves comfort. So if you want the warmth and comfort of merino wool along with the durability and wrinkle resistance of polyester, this fiber is for you.




We substitute Coolmax® polyester in the new SS22 models for Coolmax® Ecomade. Coolmax® EcoMade technology provides the same reliable cooling performance you expect from the Coolmax® brand, but it’s made with 97% recycled resources to help the environment. This polyester fiber is made with 100% recycled PET bottles. It offers permanent moisturewicking performance.


Is a new Lorpen fibre used in our new SS22 T2 styles, coming from Unifi® based in 50% polyester Sorbtek® and 50% of polyester Repreve® 100% recycled from plastic bottles. This yarn wicks moisture outside of the skin 3 times faster than other competitors thanks to its Catch-Move-Release™ technology.


In the new styles for SS22, we substitute standard Nylon used in reinforcement areas, and Nylon mixed with Lycra for adaptability, for recycled nylon coming from fishing nets whose life for the fishing industry has come to an end and instead of becoming a danger at the bottom of the sea or garbage elsewhere, they are recycled into a new nylon yarn.
