Breeze-blocking and highly breathable.

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.

Beautiful Styling! Careful with the fit

  • Familiarity: I've put it through the wringer

I'm 5-8, 160lbs. Chest 42,Waist 31
I chose a size XXL according to size charts. The fit is good in the chest, but baggy in the arms and waist line. I would have preferred a more form fitting jacket, but I'm still satisfied.
On the plus side. Kept me warm on a 3 hour ride in 52F yesterday. Just a Gore base layer underneath. This is a very nice looking jacket with great visibility. My other jacket in a Castelli Gabba 2 Convertible which keeps me fairly warm but doesn't wick the sweat away from my skin. This new jacket does wick the sweat away.

Great style, runs exceptionally small

  • Familiarity: I returned this product before using it
  • Fit: Runs small
  • Size Bought: XL and XXL

I first ordered the XL, then the XXL. Both were much too small, particularly across the shoulders. This is an Italian brand so order at least one size up, if not two.
