The only thing worse than getting caught riding in a cool mist is wearing a rain jacket that seals in body heat and moisture. Even if the rain doesn't wet you, your own sweat will. Castelli's Velo Jacket is a lightweight solution which features breathable fabric and ventilation ports all in a small, portable package.
The Castelli Velo Jacket was sewn from Forcefield fabric. This extremely lightweight fabric is a 30 gram, ripstop material that is windproof and water-resistant. It's so light, in fact, that you'll barely notice it against your skin. Additionally, it is highly breathable so that when you are working up a sweat you won't get drenched from the inside-out. The Velo jacket features covered ventilation ports on the sleeves and the back to help exhaust heat away from your body. It should be noted that while the Velo jacket is ideal for drizzle or windy conditions, it does not feature fully taped, waterproof seams.

Cut with a longer back, the Velo jacket helps to keep splash off of your behind. A high mesh collar keeps drizzle from running down your neck, and when the sun comes out, the neck turns into a pocket in which to store the entire jacket. It only takes up half a jersey pocket so it's perfect to carry on those ""what if"" weather days. Castelli added a reflective logo and back tabs to increase your visibility in low-light conditions.
Castelli's Velo Jacket is available in six sizes from Small to XXX-large and in four colors: White, Orange fluo, Lime, and Black.
