CHPT3 SSWBL 1.84 this classically styled Tee in technical wool makes a great casual piece as well as a great winter base layer.

David Millar on the CHPT3 SSWBL 1.84 ; The Short Sleeve Winter Base Layer is a staple item of every cyclists winter wardrobe. Sometimes we have no choice but to venture out when it's cold or wet, or worse, when it's cold and wet. That's when the SSWBL is dug out from it's summer hibernation.

My experience has proved that when it comes to winter base layers it's hard to beat the benefits of good old-fashioned wool, problem with wool is that although it performs well under normal circumstances it doesn't handle the requirements of high performance quite so well. For this reason we have used a new technology that involves wrapping a nylon core with merino wool which makes the fabric com er, stretchier, drier, warmer, stronger and tougher than normal wool. It's surprisingly light for its warmth, and warm for its weight. The traditional downsides of wool - stretching and twisting with age, have been eradicated.
It's designed for cool weather riding and is to be worn directly against the skin where it works as a great wicking rst layer. We've designed it more like a classic sweatshirt (a staple of every wardrobe) than a tech piece.
This is because during my racing years I would often wear my SSWBL's off the bike, for this reason we added design details to the CHPT 3 SSWBL that enable it to be worn off the bike as well as on it. The cut is close-to-body but not skin tight, after all, it's too good to be used just for cycling.


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.
