Light, windproof and stylish, wear the new SIROCCO and MISTRAL windbreakers!

Autumn is here, it's time to get equipped and protect yourself from the cool wind of mid-season, from its cool mornings and descents of the collars.

Two windbreakers with exceptional technical features, a crystal membrane weighing only 65 grams for an unprecedented lightness combined with anatomical sleeves to offer you supreme elegance.

The Sirocco windbreaker is available with long sleeves to cover the whole upper body during your bike rides and with short sleeves for warmer periods.

New this year is the Mistral cycling windbreaker, the all season sleeveless windbreaker to have in your cycling wardrobe!







Why create a Sirocco windbreaker? The windbreaker is the essential piece of clothing in your bike wardrobe and too often neglected by cyclists. We have designed for you, ladies and gentlemen, a windbreaker so light that it folds and stores easily in the back pocket of the jersey.

A unisex windbreaker with modern and unique designs.

For you ladies, the windbreaker being very close to the body, we advise you to choose a size lower than your own.


The Strech Mesh fabric on the back provides ventilation so you don't get hot and air circulates properly during your efforts.

It's not only its technicality that you will love! And yes, this new jacket with carbon and metal effects, perfectly fits your silhouette thanks to its anatomical sleeves, to offer you a unique and refined elegance.

A little extra of this exceptional windcheater: a reflective elastic at the hips to guarantee you safety on the roads.

Geoffroy Lequatre, founder and designer of the G4 brand, designed the Sirocco windcheater in France and made it with 100% Italian materials for supreme quality.
