The Azzurri will take part in the event in Brazil in June, a preparation for the 2014 World Cup, after finishing runners-up to reigning world champions Spain at Euro 2012.
Italy will meet the likes of Asian Cup winners Japan and CONCACAF Gold Cup champions Mexico in the group stages of the summer tournament while Spain, Brazil, Uruguay or Nigeria could be waiting in the knockout rounds.
It will be an extra special competition for Italy as they will wear a new national team kit, which has been created by PUMA and will be introduced for Thursday's friendly against Brazil.
Juventus star Chiellini is understandably looking forward to the Confederations Cup and also the prospect of the new kit.
"It is a great moment to wear a new Italian national team kit for the first time on the pitch," said the defender at a launch event at Coverciano, Italy's training ground.
"The design is very impressive, especially the way the colours of the Italian flag have been incorporated.
"It fills me with pride to wear this Italian shirt and I am excited about the prospect of representing our footballing nation in the upcoming Confederations Cup in Brazil."
For the first time in PUMA's history, the replica shirt is made from 100 per cent recycled Polyester, representing a further step in the Sportlifestyle brand's sustainability strategy.
The official Italy team kit features enhanced moisture management through the use of a fabric made of recycled polyester and Cocona®, which is an activated carbon made from coconut shells.
Additional details include the 'Tricolore' coloured cuffs and inserts at the bottom of the shirt that represent the national flag of Italy.
