Scandinavian Leather

full-grain leather from scandinavia woolnut
Available in

We use full-grain leather of Scandinavian origin. The leather is tanned under Gold-rated Leather Working Group (LWG) environmental protocols, their highest rating. Our leather is well known for its exceptional quality, much due to the mild northern climate of countries like Sweden, along with farmers complying with the highest standards of animal welfare in the world. The rich pebbled leather texture will age slowly over time.

100% Natural Wool Felt

We use 100% natural wool felt sourced from a renowned supplier in Germany. The supplier has been a leading manufacturer of classic wool felt for more than 120 years. Wool is a timeless and sustainable material. It is soft to the touch, with water-repellent and shock-absorbent properties – making it a beautiful and highly functional lining material that we use for a range of our products.

Matte Polyurethane (PVC & PFC free)

Some of our products use components such as small rivets or buckles, but our most used component is unarguably the zipper. The main zippers we use are YKK’s EXCELLA and METALUXE.

YKK’s EXCELLA Metal Zipper

We use YKK EXCELLA metal zippers, made in Japan, for most of our zipped leather products. The EXCELLA is YKK’s highest grade metal zipper, and well-known as one of the world’s most exclusive zippers. The zipper elements are individually and fully polished to ensure a super smooth zipper movement. This also gives the EXCELLA anti-scratch capabilities that work seamlessly with our products made to protect tech devices. We use EXCELLA zippers in a shiny silver finish. Read more.

YKK’s METALUXE Plastic Zipper

We use YKK METALUXE plastic zippers for some of our products, mostly our synthetic product lineup. The METALUXE is one of YKK’s premium plastic zippers, made to resemble metal zippers but with characteristics of plastic zippers. The METALUXE has a luxurious metallic look with shiny elements, sharp lines and a slim build. Even so, it is much lighter than metal zippers. Since it is made of plastics, it will not risk scratching your device. We use METALUXE zippers in an antique silver finish.


We do not only think twice about sourcing the best materials for our products alone. Packagings and complimentary wrapping of products are also sourced with environmentally sustainable materials that are recyclable and look great.
