Designed specifically to be worn under the 1.24 Monzamilano jersey the 1.81 Baselayer is happily also the perfect base for all your riding between April and October.

This microfibre polyester fabric has been made as light and soft as possible. Its hydrophilic outer layer wicks moisture off the skin to the jersey yet doesn't absorb moisture along the way. We made it a perfect weight so that when paired with the 1.21 jersey you end up with the combined weight of a normal looking jersey only with much better comfort and moisture management.

Monza Milano? having a TT on the final stage of a Grand Tour is not enjoyable, never has been, never will be. Unless you win it, then it’s a euphoric day, that’s what happened to me on the final stage into Milan in the 2011 Giro. We started in some nondescript industrial estate that day, the 2017 Giro sees a much more iconic start, the Autodromo Nazionale Monza, built in 1922 it was the third purpose-built motor racing circuit in the world. We pay homage to this by creating a design of the Monza start line, arguably more important to the vast majority of the peloton on the last day than the finish line, because simply still being in the race on that last day of a GT is a massive achievement in itself.

In 2015, the Chpt3 project provided the newly-retired David Millar, and designer Richard Pearce, with the opportunity to work alongside long-time sponsors to create something truly different and exclusive. A collaboration with Castelli launched the brand; a collection of lovingly designed cycling garments that fuse the latest material technology with a sartorial elegance opposed to the billboard stylings of the peloton. The result is the ultimate in both performance cyclewear and coffee-stop chic. Read more about CHPT3.
