Your intended activity, its intensity, and duration set the requirements for your shell. The higher the activity intensity, the more breathability you want. But higher breathability means less waterproofness. Fully waterproof jackets have greater fabric resistance, which keeps you warm and dry, but reduces moisture-wicking efficiency.

– For high-output activities like trail running or fast trekking, light wind protection and breathability is the key factor.

– For lower-intensity activities such as hiking, wind- and waterproofness becomes more important.

All our shell jackets use the MFR System (Mass Flow Resistance System) — a scale that measures the balance between air permeability and fabric resistance. MFR ranges from 2-10, with 2 having limited wind resistance, and 10 being fully wind- and waterproof.

Watercolumn
The water column rating shows how long you can stay outside in heavy rain without getting wet. Our waterproof jackets all have a water column of >20,000 mm, ensuring reliable protection in any weather.

Layers
Our waterproof jackets, with MFR10, are made from polyamide or recycled polyester, using 2.5-layer to 3-layer constructions with our proprietary waterproof and ventilating Cutan® technology. Each jacket consists of an inner fabric, a fluorocarbon-free waterproof membrane, and an outer fabric. These layers are laminated into a single material that is soft, flexible, and have light stretch.
