Castelli Prologo 4 Short Sleeve Jersey

Castelli's Prologo 4 Short Sleeve Jersey combines the Italian manufacturer's iconic design with some of their most cutting edge technology. With superb Stratus Plus 2-layer fabric, which actively moves moisture away from your skin and a laser-cut chest logo, this jersey will have you looking and feeling fantastic as you blitz up those hills.

The Prologo 4 Jersey's Stratus Plus fabric is made of 100% polyester that utilises a multifilament inner layer to wick moisture to the jersey's microfibre outer layer for optimal evaporation and body temperature maintenance.

Mesh side and lower back panels also help the rider maintain a comfortable body temperature level. The jersey has three rear pockets plus a zippered key pocket to keep your valuables safe.

Where the Prologo 4 really stands out is its fantastic looks. Available in several unique and stunning colour schemes, the Prologo 4 has a look to fit with any outfit and will look fantastic as part of any rider's ensemble.

The cleanly constructed laser-cut logo is both understated and eye-catching and overall the Prologo 4 is a great jersey that suits almost any kind of riding in a wide variety of weather conditions.
