BREATHABILITY AND WATER RESISTANT GUIDE


WATER RESISTANT MATERIAL

Water resistant material keeps water and snow out and the body dry and warm. Water resistance is measured in the amount of water, measured in millimetres, that can be pressured on the material before water seeps through. Coating the textile with a water resistant membrane creates water resistance.

1000mm:
Low resistance. Normally used on cheaper products. Can be used for some practical purposes.

3000mm:
Good and strong resistance. Often used for products where the customer has high requirements for the garment’s performance and quality.

5000mm:
Great resistance. Used for products that have special needs for very good water resistance, for example, high quality rainwear.

10.000mm:
Extremely good resistance. Mainly used for products that need to withstand extreme conditions.

BREATHABILITY

Materials that breathe allow sweat and moisture to be transported away from the body and out from the garment. Breathability is measured by the speed at which sweat passes through the textile, in grams of sweat that pass through a square metre in 24 hours (g/m2/d). Breathable materials are often produced by using a membrane consisting of many tiny holes. These holes are too small for a drop of water to pass through but are big enough for air molecules and thereby sweat to pass out.

Below 800 g/m2/d
Low performance. Normally used in softshell jackets. Creates comfort during physical activity.

800-3000 g/m2/d
Medium performance. Often used in ski jackets and some extra breathable softshell jackets. Also used in rainwear to make sure that the material breathes but is still water resistant.

Over 3000 g/m2/d
High performance, normally used for professional ski jackets and other garments where high breathability is important.

TAPED SEAMS

To ensure that a product is as water resistant as possible, the seams can be covered with a special tape. This tape increases the product’s properties and is used in rainwear and some ski clothing.

WASHING

It is important to care properly for products with special properties such as water resistance and breathability to maintain their high performance and durability.

Follow washing instructions closely and use only detergents or cleaning products that are specially designed for this type of material. This helps the special membrane to last longer and thereby maintains the product’s special properties longer. If not treated properly, the membrane will become damaged and its special characteristics will deteriorate.
