Product FAQs

The waterproofness of a product is measured by means of a water column. The higher the value (measured in centimeters), the more waterproof the product. All namuk products have a water column factor well above the average for commercial children's clothing.

Breathability describes the vapor permeability from the inside out, which is measured in grams per m2 over 24 hours (g/m2/24 h). The breathability of all technical namuk products is at a very high level.

DWR stands for Durable Water Repellency, and refers to a coating that is applied to the outside of our technical clothing. This coating repels water, and helps to prevent dirt penetrating into the fabric. All our technical materials are provided with a DWR coating (Durable Water Repellency).

Part of our technical collection is already completely PFOA/PFOS-free, and we are working intensively to increase this percentage further. The challenge here will be to find the right balance between “function” and “ecology”. The decisive factor is how far one can dispense with the usual product functionalities for the sake of the environment.

The onion or layering system consists of several coordinated layers of clothing. The aim is to achieve maximum function with a minimum of clothing and weight. Each of the three layers thereby fulfills a specific task, and must support the function of the underling or overlaying layers.

The layer next to the body ensures dry and comfortable wearing. It takes up the moisture arising from the body and transports it outwards. The aim is to protect the body from cooling, and therefore power loss, due to evaporative cooling. We thereby make use of a well-proven material: 100% natural merino wool, without chemical additives, which is anti-bacterial and 100% biodegradable. We only use the finest (17.5 micron), certified, mulesing-free, merino wool. Under no circumstances should the first layer be cotton, because this absorbs moisture without transporting it outwards, and, as a vapor barrier, prevents the interaction of the various layers from the very start.

The insulation layer protects against the cold by means of an insulating air cushion, and guides the moisture absorbed by the first layer further towards the outside. This is where our PrimaLoft jackets and High Loft fleece jackets are used: they can be dispensed with in warm weather, but can certainly take over the function of the outermost layer of clothing in cool but stable weather conditions.

The weather protection coating is waterproof and windproof, and protects the body from precipitation and wind. A breathability that is as high as possible ensures that the moisture that is guided from the inner layers of clothing reaches the outside and evaporates, as condensate could otherwise form on the inside.

All technical namuk products have a high breathability, and actively help to transport moisture and perspiration outwards. The different layers take on different tasks; their common feature is that that they transport moisture instead of absorbing it. Cotton, on the other hand, sucks up the perspiration, acting as a vapor barrier and thereby interrupting the complete process. It remains wet, and, as soon as you are no longer physically active, you begin to freeze.

The product specific washing instructions are attached to each product, and explain how it is best cleaned.

Please return the product to us (contact details). We will examine the problem in detail, and will contact you to discuss the next steps. Where necessary, we will then pass the product on to our repair workshop.

The higher the fill power-value, the better is the heat insulation in relation to the packing volume.
