That's because, while the sides and back are made from stretchy, jersey-weight fabric, the front features Castelli FLY Fabric Technologies (FFT). This means that, just where the elements are most likely to hit you as you ride, you will benefit from the protection of three carefully thought-out layers.

First, there's an inner of windproof yet breathable Gore-Tex InfiniumTM Windstopper®, then a layer of warmth is added by super light CLIMA SL. Finally, a FLY SL shell sheds water and deflects wind. The latter two layers, additionally, are made from 100% recycled materials, making this vest as eco-friendly as it is efficient.

To aid temperature regulation, this vest features a low/no cut collar, which acts to prevent wind from entering at the neck, without offering so much coverage that it might cause you to overheat.

It's also practical, featuring as it does some of the essential elements that make our cycling layers so good. There's ample pocket space, including a zippered valuables compartment, reflectivity and anchorage at the waist, and a top-and-bottom opening zip to aid ventilation.
