The SS19 Bio-Based Collection

The SS19 collection of knee highs, made in bio-based nylon was released in February 2019. The bio-based material is made out of oil from castor plants.

" We have been working on this collection for a long time, so it's exiting that the knee highs are finally here. It has been a process of development with research, design, finding the material, and then to design packaging and to create it. It is so nice to see it all come together into one whole, finished product. It's very interesting working with newly developed materials. The material is not just bio-based, it has so many features that pushes the boundaries of what nylon can be. So it is very exiting to finally have them in store. And to get to wear them. "

I have received several emails about the collection, so below I put together detailed information based on your questions:

About the product design
The knee highs are designed by fashion designer I.C. Renhuldt in Stockholm, and produced in Italy. The triangle on the side is building on 1800's previous collection with minimalist geometrical shapes. The seam at the toe is neat and the elastic band is flat knitted, for enhanced comfort.

About the packaging
The packaging is illustrated and designed by I.C. Renhuldt in Stockholm, and produced in Italy. It is made in soft matte aquarelle bamboo paper, with embossed black logo and illustration of knee high at front. The gouache illustrations are of castor plants, their leaves and seed capsules.

About the packaging material

  • strong and soft with an excellent elasticity
  • light, weights less than regular nylon

About castor plants
They live in areas of almost desert, so they do not take feeding ground from other animals or plants. The castor oil comes from the castor seed, that grows within the seed capsules. They grow fast, has big leafs and can reach sizes as big as a small three. Castor oil have been used for different things through out history, such as medical uses and as motor lubricants due to its great heat resistance. 
(Castor oil in Swedish: ricinolja.)
