Chelsea is an English Premier League football team. Recently they have had a great deal of success and have seen a huge increase in the numbers of supporters both at home and around the world.

Winning league and European trophies has hugely boosted the team's profile, with supporters flocking to purchase the match day kits and other merchandise including the Chelsea tracksuit.

Earlier this year Chelsea renegotiated their deal with Adidas. Adidas a German sportswear manufacturer has supplied the teams soccer jerseys and training kit since 2006.

The new deal will see this collaboration remain in place until at least 2023. The new 10 year deal is worth a staggering £300m and at the time of signing was the largest ever Premier League kit deal.

Royal blue is the iconic color of the team's home football kits. They have worn this color since 1912, prior to this a lighter shade of blue was worn.

The Chelsea training kit utilises the royal blue scheme, and includes items such as training jerseys, polo shirts, hoodies and jackets that are all worn by the team during training and prior to a football match.

As a loyal fan you can purchase these items from the Soccer Box shop now.

The Chelsea tracksuit is available in several different designs. There is a blue version that will be used for league games and at the teams training ground.

A black version has also been designed exclusively for Champions League football training and matches.

The entire Chelsea training kit collection has been developed by Adidas. Adidas pride themselves on producing high quality performance sportswear.

Keeping the body cool and dry helps to improve performance on the pitch. Look out for the ClimaCool symbol on the Chelsea training kit.

Another design element that is included in many of the Chelsea training kit items is Formotion technology.
