Nature does not judge – and since the rainbow is a symbol of diversity, openness, and equality, Fjällräven believes it perfectly captures the spirit of outdoor life. The Kånken Rainbow celebrates each individual's freedom to express themselves, and for every backpack sold, 1% of the proceeds go to projects within Fjällräven's Arctic Fox Initiative. This is a special edition pack with all the great Kånken love and a little extra. Vinylon F is uncoated, which allows it to absorb moisture better than any other synthetic fiber, causing it to swell like a natural fiber and fill the gaps in the fabric. As a result, the fabric is waterproof due to its structure, making a coating unnecessary. The outcome is a lighter and more durable material. Additionally, it has high abrasion resistance, ensuring that Vinylon F proves its durability and functionality year after year.
