Pro-level comfort and performance.

Lightweight back panel stays comfortable in the riding position and reduces heat build-up.

When the sun is melting the tarmac and you’re putting in maximum effort, overheating can sap your strength. We designed the Cosmic Ultimate SL jersey to keep you cool and comfortable so you can crank out the watts under the most extreme conditions. The key to its remarkable cooling capabilities is the lightweight mesh fabric. It’s engineered with 37.5™ technology for fast drying and unbeatable breathability. The sleeves are also designed to increase ventilation; they are so lightweight, it feels like you’re riding sleeveless. And for added protection from the sun, the fabric also includes built-in UV protection. The back panel is superlight and breathable, allowing your body to vent heat even on slow grinds up steep hills. And the Cosmic Ultimate SL features a tailored fit to prevent any flapping in the wind, improving your aero profile in an aggressive racing position. When it comes to riding gear, there is no better way to beat the heat.
