Decathlon Laboratories have developed an innovative solution to ensure maximum breathability while preserving the properties of waterproof fabrics.

The complete mechanism is based on a combination of patented solutions Equarea, Stratermic and Novadry.
The 3-layer system protects you and guarantees optimal comfort.

COMFORT: the first layer accelerates the evacuation of perspiration (Equarea)

ISOLATION: The second layer is an excellent thermal insulation (Stratermic)

PROTECTION: The third layer protects you from the weather (Novadry)

For added water resistance level of the openings, using the cerniere hinges impermeable to water.

To promote the breathability of the product in different strategic points of the head is positioned with zipper openings. The position of each fan is defined by type of use. It ‘also adopted a technology assembly (heat) that will reduce the number of seams and therefore the risk of ingress of water inside the head. Specific bands for waterproofing are finally bands of fabric and waterproof adhesive that contribute to ‘water resistance of the finished product.

In the laboratories of the manufacturer is made the following specific tests:

1: Test of water repellence

PURPOSE OF TEST: check the water repellence of the fabric, ie the ability of the fabric of the water slide on its surface.

CONDUCT OF TEST: you place a membrane mimics and the rain through a system of watering.

APPROVAL OF TEST: This test is conducted at the Technical Center of Research and Development of Decathlon.

2: Test of impermeability

PURPOSE OF TEST: check the water resistance of the fabric.

CONDUCT OF TEST: This test involves the increasing pressure of water in tissue.

APPROVAL OF TEST: waterproofing is approved if the fabric is resistant to a pressure of water defined by NOVADRY.

3: Test of resistance to chafing

PURPOSE OF TEST: measure the resistance of the fabric chafing.

CONDUCT OF TEST: This test consists of rubbing to create the fabric to be tested and a reference sample.

APPROVAL OF THE TEST: The resistance is approved if the fabric is resistant to a period of time rubbing defined by NOVADRY.

As raw material for polymer pellets, petroleum derivative, is used depending on the composition desired for the fabric. Esso è fuso per formare una pasta omogenea. It is time to form a homogeneous paste.This is then passed through a perforated plate to create the thread that suffers the following other stages of refinement before being stored on reels. The wire is then woven or worked on the basis of technical and aesthetic characteristics desired and the form of rolls stained in the color you want. The fabric becomes waterproof when you apply a thin polymer film on its inner side.The breathability is preserved thanks to the ability of film to let the steam. To allow water to slip on the surface, apply a chemical treatment to the fabric. Without this step, the tissue would increase water and transpiration would be altered.
