The lightweight aero package might make you think it's not up to much, but Castelli's wind and water resistant vest is a beast when it comes to cutting wind and protecting against the elements. A high collar keeps wind out, and a lower-back splash guard protects from wheel spray. Temperature regulating fabric is used in the back to keep you comfortable regardless of the temperature.
- Windstopper X-Lite Plus fabric on the front and shoulders offers up lightweight wind proofing and protection from the rain. Made from a blend of polyester, elastane, and synthetic fluoropolymer (PTFE)
- Backside Velocity fabric is polyester for ample movement and temperature regulation
- Heat overlay across the lower back protects against wheel spray so you don't need to worry about a skunk tail when you're walking to the podium
- Vest packs up small so it can come on every ride
- Full-length YKK Vislon zipper for easy self-venting
- Rear reflective trim at hem keeps you seen in low-light conditions
- Castelli rates this vest as best for 10-18°C
- Wash in cold water. No bleach, no steam ironing, dry cleaning, tumble drying, or fabric softener
