The Gabba jersey changed cycling, but we--like many others in the cycling world--had some critiques. For example, unless it's raining and in the low 40s, many of us find the Gabba too hot, so Castelli made the Perfetto Light Jersey to accommodate those of us whose engines tend to run hot or who want a lighter layer of protection for rainy days in Castelli's recommended temperature range of 50-68 degrees Fahrenheit. It's maybe the most versatile member of Castelli's rainy day race jersey collection, so it's returning this year with no major changes outside of colorways. Like its predecessor, the latest Perfetto Light includes a lighter version of Gore's Windstopper fabric than the classic Gabba--namely, a Windstopper 150 fabric on the front panel, sleeves, and yoke. This is a full 25% lighter than the material used on the Gabba, allowing this jersey to cover much of the range and offer similar protection as the Gabba, while better suited for warmer temperatures, and frankly, it better meets the demands of the conditions we are more likely to see in competition. The soft, 4-way stretch material doesn't let the wind in, but it does let moisture and water vapor out. This breathability and weather protection lends itself well to high output activities in variable conditions. Castelli also still uses Nano Light Pro fabric on the back, which is the same material used on the Nano Flex tights, sans fleece backing, that sheds water and allows significant breathability. Three rear pockets allow for plenty of room for food and extra gear, while laser-cut holes allow for water drainage. The pockets also deviate from accordion-style construction between pockets and jersey for a more refined look and ease of access. Below the pockets, an extended storm flap offers additional protection from wheel spray. Other details include an articulated collar preventing any looseness and water and wind ingress while riding and a front zipper featuring an external flap for extra protection....
