Castelli Fly Thermal Jacket

The Castelli Fly Thermal Jacket is the garment of choice for riders who want a bit of warmth and protection from the elements on a cold day, but also crave the freedom of an outer that is featherlight and easily forgotten, so they can focus on enjoying the experience.

It takes advantage of the one of the brand's latest innovations, Castelli FLY Fabric Technologies (FFT). This three-layer system will keep you warm, block wind and shed water, while being super light and eco-friendly.

Constructed from the inside out, the material starts with a Gore-Tex Infinium^TM Windstopper® layer that fends off wind from your chest, while being breathable and allowing moisture to escape.

Next comes a 100% recycled material layer, Clima SL, which is a featherlight layer of insulation that is nonetheless very warm.

Finally, the top FLY SL layer, which is also made from fully recycled material, blocks wind and is treated to shed water, so that you'll be protected from light rain and road spray as you cycle.

Besides this special material, the ultralight jacket, which weighs just 274g, incorporates all the practical features that you'd expect from a Castelli cycling outer. These include three useful back pockets and a zippered valuables pocket, elastic and silicone to keep the hem in place while riding, reflective tabs and a zipper that opens from the top and bottom for easy venting on the move.
