Taking centre stage this year is the co-branded collection created in partnership with K-Swiss, the tournament's Official Apparel and Footwear Partner, which also provides clothing and footwear for the tournament staff. A brand synonymous with tennis for decades, K-Swiss outfits leading players including Andrey Rublev, Ekaterina Alexandrova and Tomás Martín Etcheverry, who is also competing in this year's tournament.
K-Swiss has joined the Plava Laguna Croatia Open Umag as the tournament's Official Apparel and Footwear Partner. This year's event brand's ambassador is Tomás Martín Etcheverry, who arrives in Umag as the tournament's third seed.
Visitors can choose from red and blue cotton T-shirts, a white polo shirt, caps, towels and bags – all inspired by the tournament's sporting heritage and the distinctive K-Swiss aesthetic.
The ATP Shop also offers the tournament's Official Ball by Decathlon, available in four-ball cans and designed for both hard and clay courts. Designed to deliver balanced feel, excellent control and lasting durability, they are an ideal choice both for recreational players and regular practice. The range is completed by medium-sized souvenir tennis balls, jumbo souvenir balls for those looking to take home a memorable keepsake from the tournament, and a branded canvas tote bag.
The ATP Shop is open throughout the tournament, with official merchandise available to all visitors wishing to take home a lasting reminder of the 36th edition of the Plava Laguna Croatia Open Umag.
