Almost as bad as getting caught in a storm minus a jacket is riding in a shell that retains body heat and moisture. Castelli's Velo Women's Jacket is a lightweight, portable solution that features a breathable fabric and ventilation ports to prevent a soggy mess. Sewn from Forcefield fabric, an exceptionally lightweight 30 gram, ripstop material that is windproof and water resistant, the Castelli Velo Jacket is so light that you'll barely notice it's there. Additionally, the Women's Velo jacket is highly breathable and features covered ventilation ports on the sleeves and the back to exhaust heat and to prevent getting drenched from the inside out. It should be noted that while the Velo is ideal for drizzle or windy conditions, it does not feature fully taped, waterproof seams if you need to keep a deluge at bay, take a look at Castelli's rain jackets. Cut with a longer back, the Velo jacket keeps road spray from dampening the ride. A high mesh collar keeps precipitation from running down the neck, and when the sun comes out, the collar turns into a pocket to store the entire jacket. It only takes up half a jersey pocket, so it's perfect to carry on what if weather days. Castelli added reflective logos and back tabs to the Women's Velo Jacket to increase low light safety. The Castelli Velo Jacket Women's is available in five sizes from X Small to X Large and in the colors Black, Lime, and Orange Fluo.
