A lightweight vest serves as a critical layer when the weather can't seem to make up its mind. That's exactly why Giro developed its version of the Wind Vest as a staple in the new apparel collection. This lightweight vest was made using a durable ripstop nylon, which effectively blocks those chilling winds from reaching your core. A vented panel was strategically placed along the back, serving to evacuate warm air and moisture buildup from within. The result is a superlight outer layer that keeps your torso shielded from icy air. And when you've successfully conquered that dicey descent, simply unzip and stash it in a jersey pocket the lightweight design packs down nicely. Finishing off the vest are reflective accents throughout, as well light elastic treatments at the arm holes and hem. The Giro Wind Vest Women's is available in sizes X Small to X Large and in the colors Blue Midnight, Castor Grey, and Grey Ridge.
