Isadore Echelon Ultralight Aero Jersey, December Sky
Designed for cyclists who demand absolute minimal weight without compromising performance, the Echelon Ultralight Jersey is a true masterpiece of aerodynamics and technical precision. Every element—fabric, trim, and construction—has been meticulously refined to deliver an ultra-lightweight, second-skin feel.
Crafted from a high-density, ultralight woven fabric with a high elastane content, this jersey offers exceptional compression while maintaining breathability. Its microperforated structure enhances airflow, making it the ideal choice for intense climbs and high-output rides. Featuring the same aero-inspired fit as the Echelon Aero Jersey, it delivers a sleek, race-ready silhouette that moves seamlessly with the body under peak performance.
Minimalist in design yet bold in purpose, the Echelon Ultralight Jersey boasts bonded hems on the sleeves, bottom hem, and collar for a smooth, frictionless finish. A narrow silicone tape at the hem ensures a secure fit without unnecessary weight. Completing the jersey’s ultralight construction is the YKK® NATULON® lightweight tape zipper, providing effortless adjustability without adding bulk.
