Technical Guide

The raincoat is a must-have in the Danish weather, but what should you pay attention to when buying a raincoat?

We have made a guide so that you are ready to choose the right raincoat.


A coat's waterproofness is measured in water column pressure. The water column pressure a raincoat can withstand is indicated in MM over 24 hours. A coat is described as waterproof when it can withstand a water column pressure of over 3000 mm in 24 hours.


Technical raincoats are made by putting 2 or 3 layers of different materials together. An outer layer, which is chosen based on criteria of wear resistance, sensitivity to light, comfort and, of course, look, as well as an inner layer consisting of membranes or coatings. It is these membranes and coatings that primarily define the jacket's waterproofness and breathability.


For a raincoat to be waterproof, you must ensure that it is not only the material that is waterproof, but that the seams are secured with tape where the sewing machine has made needle holes.

A rain jacket is manually taped one at a time by an employee. It is a specialized process that requires skilled employees, the right machines and years of know-how.


In addition to the waterproof membrane on the inside of a raincoat, a surface treatment is made on the outside, which is water-repellent and makes the coat not feel wet and heavy. It is common to use a surface treatment that contains fluorocarbons, but as it is harmful to the environment and therefore to people, we only use fluorine-free coating.


Last but not least, we think it is important that you and we can trust that the raincoats you sell have been produced properly, which is why Danefæ only cooperates with BSCI certified factories. This means that we know that the working conditions for the employees are good.
