POLARTEC® x SPORTFUL VESTALPHA

The POLARTEC® x SPORTFUL VESTALPHA base layer vest is engineered to deliver high-performance insulation and advanced thermoregulation for cyclists riding through the shoulder seasons and into winter. Made with Polartec® Alpha®, a patented active insulation fabric originally developed for the U.S. Special Forces, this technical piece manages moisture and body heat like no other. It keeps you warm when stationary and dry when in motion—ideal for variable weather conditions. Lightweight, compressible, and fast drying, the VestAlpha features a front zipper for easy on and off, making it incredibly convenient to adjust mid-ride. It’s designed to be worn in multiple ways: directly on the skin, over a lightweight base layer, or under a windproof vest for added warmth. Thanks to its low-profile cut, it disappears under your outer layers, staying out of sight and out of the way—while working hard to keep your core comfortable. This exclusive piece is part of a Fresh Drop created in partnership with Polartec®, celebrating innovation and a long-standing collaboration between two leaders in technical cycling apparel. For riders who embrace changeable conditions and demand the best in breathable warmth, the VestAlpha is an essential layer.
