Sportful didn't design the Allure Thermal Jersey as a one trick pony. Instead, it starts life as a standalone, cool weather jersey in the early fall, converts into an outer layer as fall progresses into winter, becomes a base layer during the coldest months, and reverses that process with the coming of spring. The Allure Jersey strategically combines two fabrics, Thermo Flow and ThermoDrytex XP, to provide elements of insulation, weather resistance, and aerodynamics. Thermo Flow is an insulating, breathable material that's also dimpled to control turbulent drag across your body. This keeps the displaced air attached to the material's surface, preventing the premature detachment that results in areas of drag inducing stalled air. ThermoDrytex XP is also insulating, but it omits Lycra for increased wicking. The combination is a jersey that keeps you warm and dry, too, statuses that go hand in hand when the temperature starts to drop but your cycling ambitions stay high. The zipper and knit band across the chest introduce contrasting colors to the jersey, and three rear pockets with reflective highlights store your ride essentials while helping to keep you visible in low light conditions. The Women's Sportful Allure Thermal Jersey is available in six sizes ranging from X Small to XX Large in the colors Blackfuchsiaplum, Fuchsiaorangeplum, and Marine Bluelemoncyan.
