The 51-year-old designer - who founded his eponymous fashion house in 2005 - has partnered with the Pinault family to create a "functional" capsule, which will feature 50 to 60 pieces; from puffer jackets to sweatshirts and tracksuits, as well as swimwear, and will be unveiled in January 2018 and available to buy in June next year.

And the creative mastermind believes the new range will still remain "faithful" to the iconic styles of the brand.

Speaking about his latest venture, the Italian mogul told WWD: "It's a capsule collection where we will express a more functional side of the brand, while remaining faithful to the atmosphere of contemporary chic that is part of its DNA."

Giambattista is excited to introduce "new materials" to the company in the upcoming collection.

He explained: "I love the idea of introducing new materials to activewear by applying the house's know-how in handling certain fabrics to this segment. It's extremely Valli, extremely sophisticated, extremely luxurious -- but on the other hand, today's customer mixes Uniqlo with luxury brands."

But the entrepreneur insists the forthcoming drop will not be a "secondary line", as it will be integrated with other merchandise he created.

He said: "This is not a secondary line.

"We really want to develop the brand in every direction."

Giambattista has admitted his latest venture is "just the start" of the brand's development.

He said: "This is just the start.

"Over 12 years as an independent label, I created a niche for this house. It's nice to be able to apply that formula, that magic, to products that are a little unexpected for the brand."
