Common sense would lead you to believe that a warm, windproof jacket isn't highly breathable and moisture wicking as well. Designed to turn that notion upside down, the Sportful Men's Gruppetto WindStopper Partial Jacket offers warmth, wicking, and windproof protection from the elements. This versatile three season jacket is identical in fabric to the highly acclaimed Bodyfit Pro Jacket, except for the addition of ThermoDrytex XP along the back for high levels of breathability and increased moisture transport. By eliminating Lycra from its composition, ThermoDrytex XP quickly evacuates built up perspiration in the form of water vapor. Ultimately, this enhances thermo regulation for a pleasantly dry, comfortable feel, even on the fastest, most grueling rides of the year. The body of this jacket is constructed from WindStopper 4 Way Warm fabric for total windproof protection along the leading edges of the jersey i. e. the side that bears the brunt of wind resistance. This helps to keep your core temperature up when you're riding into strong headwinds and bone chilling breezes in fall and spring months. Plus, as its name suggests, this fabric facilitates freedom of movement with its 4 way stretch characteristics. Along the jacket's cuffs, you'll find ThermoDryTex Plus for extra flexibility, thanks to its ample dose of Lycra. Other functional features include a full length YKK Vislon zipper for proper ventilation, as well as three high capacity rear pockets for cavernous storage of energy gels and extra layers.
