We carry out a comparative study in a thermal laboratory in walking conditions in light winds (5 km/h).

The comfort temperature is the calculated air temperature where 70% of users have a "slightly warm" thermal sensation.

For this jacket, it’s -8°C.

However every individual feels the cold differently.

The waterproofness of a fabric, provided by a coating or membrane, is measured in Schmerber or mm H²0 (pressure exerted by a column of water). The higher this number, the more waterproof the fabric.

This jacket has a waterproof component (JIS 1092 standard) resistant to 15,000 mm H²0 (Schmerber) before washing. As such, this waterproof jacket protects you from a shower, i.e. 6 cm of rain in 1 hour.

To dress properly in winter, whatever your activity, we recommend using the 3-layer principle:

layer 1: The high-tech base layer transfers moisture away from the body to keep your skin dry.

layer 2: The second layer (fleece, sweater) provides warmth and transfers moisture outwards.

layer 3: The jacket protects you from the outdoor conditions: rain, snow, wind.

The whole outfit must be breathable in order to eliminate moisture.

The seams of a jacket can be taped to prevent water from entering that area.

Here, the main seams are taped, which matches the seams of the hood, collar, shoulders, armholes and chest.

The fabric is made waterproof and windproof by applying a coating or membrane to the inside. Indeed, a waterproof fabric has the necessary technical characteristics to be considered windproof. Wind protection is very important because of the significant chill effect that wind can have on the body, whether you are active or at rest.

A fabric's water repellent property is its capacity to make water run off its surface without seeping in. This prevents the fabric from soaking up water and keeps it lightweight, warm and breathable. The water repellent property is achieved by treating the fabric's exterior. This treatment must be renewed throughout the garment's lifespan (recommended after each wash). Products (spray or liquid) for this purpose are available in our stores.
