Originally designed for the rigorous needs of the Tinkoff Saxo pro cycling team, the Sportful Men's Gruppetto Thermal Long Sleeve Jersey delivers the lightweight warmth, stretchable fit, and aerodynamic cut that's demanded by the pros. The Gruppetto is identical to Sportful's Bodyfit Pro Jersey in fabric. However, its color schemes and asymmetrical patterning are much bolder, helping you stand out from other cyclists on the road. ThermoDrytex Plus along the shoulders and sleeves combines maximum stretch with fleecy, insulated lining for added heat retention. The body is made of ThermoDrytex XP for high levels of warmth. Unlike the stretchier ThermoDrytex Plus along the sleeves and shoulders, the body's ThermoDrytex XP fabric forgoes Lycra to enhance moisture transport and evaporation. Other key features designed to enhance fit and performance include a silicone gripper along the waist, dropped rear hem for extra coverage in the riding position, and three high capacity rear pockets. You'll also find a full length YKK Vislon zipper for premium quality and extra ventilation. Note that this jersey features an ergonomic, close to body fit for aerodynamic performance.
