The Castelli Chpt.III 1.21 Short Sleeve Jersey has been designed by David Millar to provide riders with an ultra-lightweight jersey with the aesthetics of a bespoke piece of clothing. From Millar's Chapter 3 range, this Jersey's button collar, shirt tailored fit and strategic reinforced pockets mean this is one of the most darting, stylish and unique jersey's that you will see out on the road.

Castelli Chpt.III 1.21 Short Sleeve Jersey

The Castelli Chpt.III 1.21 Short Sleeve Jersey provides riders with a super-lightweight tailored jersey with a unique button collar and six strategic pockets. The proprietary material used in the jersey's construction is lighter than that used by pro-racing teams as it can not be printed on, therefore making it impossible to carry a sponsors name; normally not the concern of the amateur cycling enthusiast.

David Millar wanted the jersey to have a more tailored cut than the average race jersey. By darting the front panels and sharpening the shoulder's edges, a fit more similar to a shirt rather than a t-shirt was created.

In addition to this is the buttoned collar, which gives the jersey a higher and more substantial neck while also imbuing the jersey a more bespoke appearance. A collarbone button provides an anchoring point for the collar flap, should you decide not to use it, and a front storm flap pocket is ideal for carrying valuables.

The central rear pocket is well suited to carrying bulkier winter garments such as the Rocka 1.61 jacket and the stitching on this and the other pockets is reinforced to cope with the occasional times that they are stuffed.

David Millar: "There are two mesh pockets on the interior rear of the jersey to carry warmers if need be - when racing we’d often stuff unwanted clothing up the inside of our jersey, this is a more refined version of that."

A subtle full-length front zip provides ventilation and the subtle Chpt.III graphics on the sleeve and rear help to boost your visibility in low-light situations. Holding the whole jersey in place are the detailed hem grippers.

Available in two colour schemes, this ultra-stylish jersey will certainly be a unique and prized addition to any rider's wardrobe.

PLEASE NOTE: The Castelli Chpt.III 1.21 Short Sleeve Jersey follows the same inch sizes as you would see when purchasing a shirt as this helps to provide a more personalised fit.
