As a bike rider it’s inevitable you’ll have days on the bike where clouds blanket the sky and the rain barely relents for the whole of your ride. The Slicker Pro Jacket is just for such days. The superlight Microshell 2-layer ultralight waterproof/breathable fabric is key to keeping you dry and comfortable. Not only good at keeping the rain out, but the external membrane also ensures incredible breathability, preventing you from wetting out with sweat. Fully taped seams prevent water from seeping in, while a YKK Vislon waterproof zipper allows full control of ventilation. With stretch body panels and sleeves, Castelli have kept the fit close and streamlined, preventing flapping that could otherwise waste precious energy. Stretch wrist closures also keep out the elements and work well with rain gloves too. Because this is a jacket you might be wearing for a while, Castelli have added back pockets for easy access to your essentials. The pockets also feature drainage holes, so they don’t fill up with water. And if clouds do break and the rain relents, the Slicker Pro packs up small, making it easy to stash away.
