Available in limited quantities, this is the lightest rain jacket in the world, yet it does not skip out on any functionality. The Castelli Idro Rain Jacket is constructed with Gore-Tex fabrics and tapered seams while also bringing unprecedented levels of durable rain protection. A YKK Vislon zipper keeps you protected at the front, whilst reflective elements throughout the jacket have been used to enhance visibility in low-light conditions.
Castelli Idro Rain Jacket
Castelli Idro Rain Jacket
Weighing only 123 grams and with the ability to fit into half of a pocket, the Castelli Idro Rain Jacket is the lightest rain jacket ever made but it doesn’t skip out on any functionality. Designed for the very worst conditions, the Idro isn’t just a quick protection cape to stop you getting wet for a certain amount of time, but a jacket to protect you in the worst conditions possible.
The Idro brings unprecedented levels of durable rain protection due to its Gore-Tex technology embedded within the construction and functionality is at an all-time high thanks to the attention to detail Castelli use within all their products.
An easy sliding waterproof YKK Vislon zipper and elastic bindings on the cuffs and hem keep the jacket in place, stopping any wind or water ingress from affecting your riding, plus a zipped opening on the back allows you to get to your rear pockets if you need to.
Reflective elements have also been incorporated to enhance visibility in low-light conditions, making this perfect for seasoned road riders looking to push their rides into the night or commuters who want more functionality out of a jacket.
Even weighing 123 grams, the Idro Rain Jacket features fully tapered seams to maintain its waterproofing through the most turbulent of weather and it still folds down into a pocket size, making it easy to stash in your jersey pocket should the sun start beating down.
