A lightweight long sleeve jersey. Built for shoulder-season miles and sun that doesn't quit. For cool starts that warm up fast, long days where conditions shift, or hot climates where coverage beats sunscreen. The Long Sleeve Aero Jersey carries the same aero fabric as the OTNR short sleeve, extended for full-arm coverage that regulates heat and blocks UV without adding drag. Built for when the day won't let you commit to short sleeves.

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.

For shoulder-season miles and high UV days. For cool starts that turn into warm afternoons, long days where conditions shift beneath you, or rides through climates where full coverage beats sunscreen. The Long Sleeve Summer Aero Jersey carries the same aero fabric as the OTNR short sleeve, extended for arm coverage that regulates temperature and blocks UV without adding drag.

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.

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

Machine wash cold (30° max)
