MEASURING WATERPROOFING

Waterproofing is measured in Schmerbers or mmH2O (the pressure exerted by a water column).

A material with a rating of 10,000 mmH2O can resist 10 metres of water.

The bigger the number, the more waterproof the fabric.

NIGHT-TIME VISIBILITY

This jacket is certified as PPE under standard NF EN17353. Cyclists can ride safely at night thanks to the certified reflective bands around the arms and torso.

The reflective parts have been positioned based on the constraints of cycling (leaning forwards, wearing a backpack, signalling with your arm, etc.) to guarantee 360° visibility at night from up to 50 m away when picked up by car headlights.

SHAPE DESIGNED FOR CYCLISTS

The 540 jacket is made for urban cyclists riding in wet weather. Its cycling-specific cut provides good freedom of movement and covers the lower back, arms, neck and wrists when in riding position to guarantee great protection from the cold and wind.

Zipped vents under the arms to let air circulate freely.

You can wear your helmet over or under the hood.

WATERPROOFING IS:

- A WATER-REPELLENT TREATMENT

A fluorine-free chemical recipe placed on the fabric's surface to make water slide off it. This treatment can be reactivated by heat (10 minutes in the tumble drier on a gentle cycle).

- A WATERPROOF CONSTRUCTION

The aim is to avoid water getting in through the holes in the seams by placing a waterproof strip under the seams.

- A WATERPROOF FABRIC

A fabric's capacity to prevent water from penetrating it.
