A formidably protective piece of kit, the Thermo Shield Jacket is designed to keep your body warm during high intensity rides in sub-zero temperatures or strong winds. Insulating and breathable, Thermo Shield is the ultimate choice for high-intensity rides, intervals in start-stop conditions, climbs, descents, low temperatures and changeable conditions. It's crafted with Polartec® Alpha®, a proven temperature-regulating fabric known for its active insulation and ultra-high breathability, which rewards the rider as the effort intensifies.Constructed to actively insulate, this advanced fabric teams the ability to regulate the core by trapping and sealing in warmth with a hydrophobic outer meaning it releases excess body heat and moisture and dries rapidly before the rider gets any sense of clamminess. The design is rounded out with a windproof exterior and treated with a durable water repellency (DWR) finish for exceptional protection from the elements. Cut with just the right amount of freedom of movement, Thermo Shield relies on a form-following, performance-focused fit. Small essentials Reflective details let you ride freely and comfortably at all times.
