This season, our award-winning proprietary material, Eco-Shell, is joined by High Coast Hydratic Series, bringing on-trail functionality to everyday activities. Eco-Shell and Hydratic products are similar; they are waterproof, and offer PFC-free impregnation and breathability in a sustainable and versatile package. The High Coast Hydratic Jackets and Trousers use recycled polyamide and feature a protective, nature-inspired design on the inside.

Shells keep rain and wind out, but must be breathable too, by letting moisture from your body to readily escape through tiny pores. Our shells use a layer system (3 with Keb and Bergtagen ranges or 2.5 with the High Coast Hydratic range) combined with a structure of microscopic hydrophilic corridors that let moisture out but don’t allow in the rain and wind.

Fjallraven offers a wide range of shells for varying weather conditions, find yours by selecting your activity below.

A decade ago perfluorocarbons (PFCs) were found in Antarctic penguins and Arctic polar bears. Fjällräven had seen enough; the product team went to work developing a shell material that was breathable, waterproof, and utilized a durable water repellent (DWR) that was free from PFCs. In 2015, using a mix of recycled and virgin polyester and a new impregnation treatment, we created our award-winning proprietary material, Eco-Shell. Since the launch, Fjällräven’s Eco-Shell collection has expanded from trekking to mountaineering and even everyday activities; and our commitment to pfc-free impregnation has never wavered.

A: The outer fabric made from recycled polyester is treated with a pfc-free impregnation that repels rain, water, sleet and snow from the face fabric.

B: The hydrophilic membrane effectively stops moisture from getting in from the outside, at the same time as it can transport moisture from the body out to the outer layer where it evaporates. At the same time, the membrane is 100% windproof from the outside.

C: On 3-layer Eco-Shell, a thin polyester tricot lining on the inside of the membrane protects it and makes it soft and comfortable against the skin. This inner layer also helps initiate the transport of body moisture through the membrane.

D: The windproof outer fabric together with the membrane stops cold winds from getting through the fabric and cooling you down.

E: On 2.5-layer Eco-Shell, a coating on the inside of the membrane protects it from wear and makes the garment soft and comfortable against the skin.

Perfluorinated chemicals, also known as PFCs or fluorocarbons, are traditionally used in the outdoor industry because they have the ability to make materials water repellent. However, they don’t break down in nature. Instead, they stay there and can be stored in living organisms working their way up the food chain.

• PFCs are suspected human carcinogens, that have been linked to cancer, kidney damage, and reproductive issues.

• PFCs are highly volatile and can travel long distances of several hundred kilometers through the air and even into remote atmospheres.

• PFCs pose human health risks if they accumulate in drinking water at levels as miniscule as one part per trillion - the equivalent of less than one teaspoon in 1,000 Olympic swimming pools' worth of water.

• PFCs have a very long biological half-life - specifically, it takes our bodies more than four years to flush out half of the PFCs currently residing in our tissues.

• PFCs virtually never go away, they accumulate in nature and eventually find their way back to us. Researchers have found the chemical in remote parts of the Arctic, in soil and dust, in fish and meat, in human tissue, and in drinking water.
