WATERPROOF FEATURE OF THE COMPONENT

The resistance of a fabric is measured by the height of a water column in mm that can be supported by the fabric (test based on the JIS 1092 standard). The higher the water pressure, the more waterproof the fabric.

A component with an impermeability rating of 5,000 mm will therefore withstand the pressure exerted by a 5,000 mm column of water (which corresponds roughly to a 1-hour rainfall). Waterproofing is expressed in schmerbers (for example: 5 000 schmerbers). This number is before washing.

Windproof effect

Coating applied to the fabric makes it waterproof and windproof. Waterproof fabric has the necessary technical characteristics to be considered windproof. Protection from the wind is critical, as whether playing sports or at rest, wind can chill the body significantly.

COMPONENT BREATHABILITY

Component breathability is measured by its thermal evaporative resistance (RET).

This is its capacity to let water vapour generated by the body during physical activity escape and therefore avoid water accumulating on the skin.

The lower the RET, the more breathable the fabric.

RET ≤ 6: very breathable fabric

RET ≤ 12: breathable fabric

RET ≤ 20: little breathability



Our product has a 12 RET rating
