The S11 generation of the GT Shell Jacket is water-repellent, windproof, and breathable – the three touchstones of adaptability that define a versatile cycling shell for all seasons. In summer, it occupies a jersey pocket for days when storm clouds threaten or long, chilling descents loom. In the shoulder seasons, it layers over mid-weight Spring Fall jerseys, adding weather protection to thermoregulation. In winter, it creates a final bulwark over a winter jacket, shielding against extreme, wet conditions. While keeping precipitation and road spray out, the jacket also expels internal moisture, preventing a stifling, humid micro-climate in summer and damp, clammy chill in spring, fall, and winter. The extended collar and hem protect your neck and repel road spray, and ultra-elastic cuff inserts create a seal around the wrists or gloves.
Technology
