Natural Fibers

Natural fibers are fibers with fragments, threads, or down originating in nature that can be spun into yarn or string. Natural fibers can come from animals (Merino wool) or plants (Tencel). These fibers have a reduced impact on nature and the environment.

Natural Fibers

Merino wool: Due to the long length and short diameter of the fiber, Merino sheep’s wool creates a softer yarn with a finer loop that is softer to the touch than wool from other species of sheep. The fiber’s core is hydrophilic (water retaining) and breathable. Since it retains heat even when damp, it is the fiber used in the middle layer of our T3 socks and the main fiber in our T2 socks for use in colder temperatures.

Natural Fibers

Tencel: Tencel® is a Lenzing cellulosic fiber from certified sustainable Eucalyptus trees. Tencel®’s nano-structure provides exceptional moisture wicking, accumulation, expansion, and drying.

Hybrid Fibers

Hybrid fibers are made up of a combination of natural fibers (from natural sources) and synthetic fibers (manufactured). Since they were designed with recycled materials including polyester, Lorpen’s new hybrid fibers are a more sustainable version of its previous fibers.

Hybrid Fibers

Merino blend: An intimate blend of Merino and acrylic, creating a comfort-boosting yarn with a pleasant feel.

Hybrid Fibers

Merino Dry: The new MerinoDry yarn has all the benefits of superfine Merino wool in addition to containing a synthetic polyester fiber that improves the sock’s moisture-wicking properties, dries more quickly, and boosts wearability.

Hybrid Fibers

Merino Dry ECO: The new MerinoDry ECO yarn has all the benefits of superfine Merino wool in addition to containing a 100% synthetic polyester fiber that improves the sock’s moisture-wicking properties, dries more quickly, and boosts wearability.

Hybrid Fibers

Recover wool: RecoverWool yarn is made of recycled post-industrial wool and recycled polyester. Blending these two types of wool strikes up a marvelous balance between thermoregulation and sweat wicking.

Synthetic Fibers + ECO Fibers

These fibers do not come from nature, meaning they are manufactured. As a company committed to the environment and reducing our ecological footprint, at Lorpen we’ve replaced the majority of our old synthetic fibers with sustainable and eco-friendly ones. That’s why the products in our SS22 collection have been designed with fibers made of recycled materials including plastic bottles, fishing nets, and more.

Synthetic Fibers + ECO Fibers

Coolmax EcoMade: Coolmax® EcoMade technology provides the same long-lasting feeling of coolness that you’ve come to expect from Coolmax®, but made with 97% recycled materials to protect the environment. This polyester fiber is made with 100% recycled PET bottles, offering permanent moisture wicking.

Synthetic Fibers + ECO Fibers

Eco Therm: Lorpen’s new ECOTherm fiber used in the T2 models comes from Unifi® and is 100% hollow-core polyester made with recycled plastic bottles. Since it is hydrophobic, it retains body heat and wicks away moisture.

Synthetic Fibers + ECO Fibers

Eco Fresh: Lorpen’s new ECOFresh fiber used in T2 models comes from Unifi® and is comprised of 50% Sorbtek® polyester and 50% Repreve® polyester, both from 100% recycled plastic bottles. This yarn wicks moisture away 3 times faster than its competition thanks to Catch-Move-Release™ technology.

Synthetic Fibers + ECO Fibers

Red-Cycled Nylon / Red-Cycled Nylon Econyl: Red-Cycled Nylon yarn is 100% made with fish nets whose useful life in the fishing industry has come to an end. Instead of becoming a hazard at the bottom of the ocean or garbage elsewhere, they are recycled into a new nylon yarn. This continuous fiber yarn is characterized by its strength and cushioning capacity. This is the fiber that is most resistant to wear and tear.

Synthetic Fibers + ECO Fibers

PrimaLoft Eco: Polyester yarn developed by PrimaLoft® (number 1 in the world in artificial thermal insulation for technical garments). It is a soft, thermally insulating, hydrophobic fiber that wicks away and does not absorb moisture. It is currently made with 70% of its contents coming from recycled resources like plastic bottles.

Synthetic Fibers + ECO Fibers

Polartec Power Stretch: Polartec® Power Stretch® is a high-performance base fabric designed for maximum freedom of movement. This four-way stretch synthetic fabric can flex and stretch during movement and return to its original shape to withstand the pressure of demanding physical activities.

Synthetic Fibers + ECO Fibers

Polypropylene: This is a polypropylene fiber whose main property is that it dries quickly while offering a nice, warm, comfortable feeling. It also affords the sock antibacterial properties and is BlueSign® certified.

Synthetic Fibers + ECO Fibers

Stretch Nylon with Lycra: Nylon is a continuous fiber synthetic yarn that is distinguished by its strength and cushioning capacity. In fact, it is the fiber on the market most resistant to wear and tear. Lycra is a synthetic elastane fiber that can stretch up to six times its length and go back to its original state again and again. Its strategic placement in the outer layer of Lorpen socks guarantees a long life for our socks.

Synthetic Fibers + ECO Fibers

PrimaLoft Bio: 100% post-consumer recycled fiber that is biodegradable. A circular technology. ASTM D5511 tested, a standard test method for determining anaerobic biodegradation of plastic materials under high-solids anaerobic-digestion conditions.

Synthetic Fibers + ECO Fibers

Sensil BioCare: SensilBioCare® is a biodegradable fabric and yarn made of very elastic nylon. It is produced so as to reduce its carbon footprint, save energy, preserve water, reduce waste, provide a safe work environment, and offer a plant powered by cogeneration. It has been ASTM D6691 and ASTM D5511 tested.

Synthetic Fibers + ECO Fibers

Econyl: ECONIL® yarn is 100% made with fish nets whose useful life in the fishing industry has come to an end. Instead of becoming a hazard at the bottom of the ocean or garbage elsewhere, they are recycled into a new nylon yarn. This continuous fiber yarn is characterized by its strength and cushioning capacity. This is the fiber that is most resistant to wear and tear.
