The Velo Vest is identical to the Velo jacket with two exceptions. The most obvious, it doesn't have sleeves like the Velo Jacket. And the other less obvious distinction, vented panels. The side panels of the vest are perforated for air flow which contrast the solid sides of the jacket that focus more on weather and wind protection.
All panels that compose the Velo Vest are anatomically correct and constructed of Castelli's proprietary and bomber Forcefield fabric. This magical fabric is windproof, water resistant and breathable. Beyond that it's is so low volume it makes the Velo vest totally packable and what we would consider portable protection. Total vest weight is around 70 grams. The shoulder ends and waist are double folded and double stitched so they are comfortable and will never fray. The full zipper operates smoothly for easy use on the bike. The top of the zipper has a flap that covers the zipper pull, so it will not rub and irritate the bottom of your chin. Medium height collar has internal mesh lining for added breathability and comfort.
The fitted and tailored style keeps flapping to a minimum which eliminates the biggest problem for a jacket in this category. The tail of the vest is slightly lower to protect you from road spray. The lower rear elastic has small silicone inlay to keep the jacket in place and water and debris out.
