A lightweight aero arm fabric reduces drag while maintaining airflow. The updated fit features a softer, wider rear waistband and a shorter body length, removing excess fabric and creating a cleaner silhouette on the bike.
Ultra-light torso panels use high-stretch fabric with exceptional moisture management. Sweat moves fast, dries quickly, and stays opaque - even in the hottest conditions.
Designed to stay fast in every position. Whether you’re riding steady on the hoods or pushing the pace off the front, the jersey holds its shape and regulates temperature when it matters most.
Three rear pockets provide essential storage. In wind tunnel testing, riding with them full saved an additional 2W at 45kph. Race ready - and proven at speed.
Usage

For the hottest days when speed still matters. For long climbs in full sun, fast group rides that turn into races, or solo efforts where overheating is the only limiter. The Lightweight Aero Jersey keeps airflow smooth over the arms while pulling heat away from the torso. A jersey that lets you stay deep in the drops without paying the price in body temperature.

Technology

Aero sleeves
Lower-denier version of the woven knitted aero fabric proven in the TT Skinsuit 2.0. Reduced weight and increased breathability for summer heat, while maintaining the same drag-reducing structure.

Front
Lightly perforated warp-knit with controlled opacity. Cools efficiently through targeted ventilation, yet remains solid enough for modesty at every angle.

Back
Open-structured mesh engineered for maximum evaporation. Moves sweat away from the skin instantly and allows heat to escape across the entire back when the effort builds.



Features
  • 3x rear pockets
  • Custom made fabrics for unrivalled aerodynamic performance
  • High cut waistline
  • Invisible zipper for minimal drag
