New for 2017 - Team Sky are delighted to form a performance kit partnership with Castelli.
Team Principal Sir Dave Brailsford said: "We're really excited to be able to announce this partnership between Team Sky and Castelli.
"Castelli will be more than a kit supplier, they will be an innovation partner. Castelli has a long history of breaking new ground when it comes to kit and design. We will continue to push hard to make sure our riders have the best clothing and equipment, and we're already excited about some of the ideas Castelli are working on with us."
Castelli will supply Team Sky's race kit, which will feature a brand new design for the 2017 season. The jersey design contains a mix of British and Italian influences, and the graphic celebrates every victory from Team Sky's first seven seasons.
The classic Breton shirt served as the inspiration but has been reimagined in a data pattern with each stripe on the jersey, short, mitts, socks and cap representing a specific Team Sky victory. The longest lines are the four Tour de France victories, with Chris Froome's 2016 victory immediately below the Sky logo on the chest.
Brailsford added: "We spent a lot of time thinking about our new kit and what we wanted it to represent visually. We wanted to find a way of celebrating the success we have had as a team, but also to make sure we keep our mind firmly on the future. As a team we still have an enormous amount of goals we want to achieve and, through the design of our new kit, those will always be at the forefront of our thinking.
"We've maintained the design elements which our kits have become well known for, such as the blue line, but produced something ambitious and unique to Team Sky.
Andrea Peron - Castelli race performance director
Castelli and Team Sky share the same drive for results-driven innovation in everything we do.
He said: "Castelli and Team Sky share the same drive for results-driven innovation in everything we do. Team Sky has a structure and the resources to help us continuously give our athletes a performance advantage.
"Whether it's aerodynamics, foul weather protection or solutions that let the riders train more comfortably, we're looking at every opportunity for an advantage."
Steve Smith, Castelli's brand manager, said: "Team Sky's relentless pursuit of results means that they expect the maximum from their technical partners. We're looking forward to being pushed.
"But the Team Sky internal performance group will be an invaluable resource to help us make sure that every rider has an advantage every time he's on the bike."
The short dashes on the jersey represent one day race and stage victories, while the medium length lines represent multi day stage races, with the number of stages determining the length of the line. WorldTour races are blue lines, while non WorldTour races are white. The front of the jersey is made up of victories by 2017 team members with the exception of Sir Bradley Wiggins' 2012 Tour win which has a special place in Team Sky history.
