T3 Pro Trek Heavyweight Crew Sock

T3 technology: 3 layers of differentiated yarn with a hydrophobic yarn next-to-skin to keep your skin dry, a hydrophilic yarn in the mid-outer side to absorb the moisture out of the skin and spread it for faster drying and a resistant yarn on the outside to protect the areas most exposed to friction.

SLS (Selective Layering System) Technology: allows Lorpen to combine different numbers of layers in different areas of the same sock as required by the activity the sock is designed for. Guaranteed thermoregulation, key for blister prevention.

PimaLoft® Recycled: a soft, thermally insulating, hydrophobic fibre that expels and does not absorb moisture, with 70% of the content made from recycled resources such as plastic bottles.

Stretch Nylon with LYCRA® adds durability and ensure these socks stay up in your shoes without slipping down to your toes. On the one hand, NYLON is a synthetic continuous fibre that is characterised by its resistance and capacity to cushion. On the other hand, LYCRA® is a synthetic elastane fibre that can stretch up to six times its length and return to its original state. Its strategic placement in the outer layer of Lorpen socks guarantees a long life for Lorpen socks. Along with Nylon, LYCRA® is characterised by its strength and cushioning capacity.

Red-Cycled Nylon yarn is made entirely from fishing nets whose useful life in the fishing industry has come to an end. In this way, instead of becoming a danger at the bottom of the sea, they are recycled to give life to a new nylon yarn. This continuous fibre yarn is hard-wearing and provides good cushioning. It withstands wear and tear better than any other fibre on the market.

Merino wool: Lorpen Merino wool is certified by the Responsible Wool Standard (RWS), ensuring the welfare of sheep and the sustainability of the land they graze. Merino wool is a breathable fibre that retains heat, even when wet. The outer cuticle of Merino wool is hydrophobic and moves water onward away from itself while the core is hydrophilic meaning it will absorb some of the water vapour and hold onto it while leaving the fibre dry to touch. It can absorb over a third of its weight in water before feeling wet.
