Arena has teamed up on a couple of initiatives with Mattel, the toy company behind brands such as Barbie, Hot Wheels, Polly Pocket and Fisher Price. The Italian swimwear company is putting out a co-branded line of clothing and accessories for the swimming pool and the beach. It will also sponsor together with Mattel the construction of a new water reservoir in a school at Mumangani, in Kenya, allowing the local kids and their families to take a bath once in a while for fun and for personal hygiene.
