Peko Resin- multi-layer sock from Nativa™ merino wool-Beige

There is an active resin-polyamide against the skin, which releases the resin onto the yarn surface in a controlled manner. 

The next layer is very warm and breathable merino wool. The outermost surface layer is durable polyamide. The healt effects of resin have been known for thousands of years.
Resin has been used e.g., for prevention of infections, treatment of wounds and athlete's foot.
Finnish Premix Oy has developed a polyamide yarn in which Prexelent technology makes the yarn active by releasing resin in to the surface of the yarn in a controlled manner.

The resin is the resin of the Finnish coniferous trees, whic is obtained as a byproduct of the forest industry. Merino wool naturally reduces the smell of sweat and dries quickly by airing.
The skin feels dry, and the moisture does not absorb into the shoes. Thanks to the seampless tip, the sock does not chafe.
Elastic knitting of the stem and tightening with the foot, keeps the sock firmly on the foot but does not squeeze.
