Giant's Superlight Wind Vest uses ultralight wind-proof fabric to shrug off the cooler temps and chills from long descents. It features a full-length zipper and vented back panel for easy temperature regulation, while the packable design fits easily into a jersey pocket when temps start to climb. There's also 360-degree reflective accents for increased visibility in low-light riding conditions and a rear storage pocket for your on-the-road essentials.
