The Cielo Long Sleeve Jersey achieves a ?balance of warmth as well as breathability, making it a versatile top for days where it may start out cool, but with conditions warming up as you ride. Warmer fabric on the body and sleeves is close-knit to keep in warmth but it's lightweight and breathable so you don't feel overheated. Warmer X-Stretch fabric to the sides provides a wonderful fit and plenty of mobility as you get in and out of the saddle.
As you'd expect Castelli also get the details right too - an easy-sliding YKK® Vislon® zipper with neck protector makes for easy on/off and ventilation control, while the dropped pocket design makes for a better fit at the waist. Lastly, reflective details add visibility as the evenings draw in. It??¢s focused and functional, making this a great-performing essential jersey for transitional months of the year.
