Packable, Lightweight Protection. The Zephyr Jacket is a semi-opaque lightweight piece that defends against wind and moisture extremely well. While this isn’t a “waterproof” piece, due to the lack of taped seams, it is extremely water-resistant. The additional piece of fabric on the back covering the shoulders also helps keep rain away on fast descents. Reflective accents on the back aid in visibility. The Zephyr Jacket easily packs into its built-in pouch to be stored in your jersey pocket. On a temperate or cool day where a strong wind or fast descent induces a performance-robbing chill, this is the ideal piece. Unisex sizing. Made in Italy.
