G4 offers you the choice of color for this brand new ultra technical cycling jacket :

Supreme in the black of excellence and prestige, and the Supreme Navy in ocean night blue, for a unique style that is always unmatched!

Inspired by the Mediterranean blue of the beautiful French Riviera, Geoffroy Lequatre imagined and designed these collections in Nice, and their production is carried out in Italy.




The Supreme & Supreme Navy long-sleeved jackets are of a formidable technicality!

They both have a breathable membrane to accentuate the evacuation of perspiration and promote your comfort.

Added to this membrane is a fabric with windproof properties to protect you from the cold and keep your body temperature at a good level.

Their anatomical cut allows an adaptation to all the different morphologies and gives you a nice look on your bike!

We also added 3 pockets, made from the most resistant fabrics on the market with elastics to hold your supplies or bike accessories. Elegant reflective fabric pockets with dots for optimal safety on the road.

All this comes with a very resistant zip and carefully hidden to avoid any discomfort.

During your cycling outings, it is important to ride with a technical jacket: good breathability will make you gain in performance!
