If you like a bright kit through and through, our Clear Night Neon Base Layer ensures you look stylish even when you’re facing a difficult climb and you have to unzip your jersey. It is an ultra-light and breathable inner layer to make you feel cool and comfortable on your rides. Made with marine blue antibacterial mesh fabric, it acts like a second skin that keeps you dry. 

Our Neon Base Layer is cleverly designed to look as if it has small neon lights flashing across it. These intricate details look particularly good as the sun reflects off the jersey. 

You’ll feel as if you’re carrying little charges of energy around with you, pushing you to ride faster.

  • Ergonomic design and fit 
  • Made of the finest Italian fabrics 
  • Mesh fabric for extra breathability and ultra-fast drying
  • Perfect fit to your body shape
