If you're looking for the ultimate all-rounder, look no further! We've used our lightest triple-layer GORE-TEX INFINIUM™ WINDSTOPPER® stretch fabric, ideal for milder weather with a stretch that provides a perfect fit. It's the same outer fabric we use on our Alpha RoS 2 jacket, which Cyclingnews.com calls the benchmark for performance among the best winter jackets. The Go Jacket forgoes the Alpha's integrated lining, giving you the freedom to choose your own level of warmth. Add a Flanders Warm base layer and a thermal jersey to extend its comfort range into sub-zero temperatures. But it's not just the fabric that makes this jacket exceptional. Its fit is close to the body, but not too tight. It drapes beautifully and features great details like a seamless hem and a colorful zippered front pocket. The concealed internal cuffs add a touch of comfort, and you'll appreciate the absence of drafts around the wrists. There are three rear pockets, with a wide reflective strip extending along the entire bottom of the pockets for nighttime visibility. Where does this jacket fit in our range? Its warmth level is comparable to the Perfetto RoS Long Sleeve, but it has a more streamlined, fitted look and a slightly more relaxed cut, though it doesn't offer the same level of protection in wet conditions.
