Geared Up: Iga Swiatek sits at the top of the rankings with Tecnifibre and On

Racquet: Tecnifibre T-Fight 300 ISO ($249)

Swiatek had formerly been using her signature Tempo 298 racquet, but decided to switch to the T-Fight 300 at the start of 2024. With its user-friendly weight and accessible power, the 300 is the most used of the T-Fights. The ISO in its name stands for ISOFLEX—it’s essentially variable racquet stiffness depending on the location of the frame to promote a wider, more predictable sweet spot that’s also more forgiving on off-center contact. The other notable design is the RS Section beam that combines a square shape to promote feel and control with an elliptical shape to produce more power. It has a firm response that offers a crisp, clean and solid feel at contact. The 16x19 string pattern helps put lots of shape on ball, which Swiatek takes advantage of on her heavy ground strokes.

Apparel: On Women’s Court Tank ($70) and Court Shorts ($80)

Swiatek put On on the tennis apparel map. Her Court Tank is made of a soft, lightweight material with a streamlined design that moves as she does. The neck and armholes are also tailored to limit distractions. The top is slightly longer in the back to provide additional coverage when she’s flying across the court. And the bold coloring makes a strong statement.

The Court Shorts have integrated tights for added security and a built-in waistband for a customized fit. Like the Tank, it’s also extremely lightweight, with a side seam slit to allow total freedom of movement. Bonded hems mean chafe-free comfort no matter how long the match goes. And a discreet zipper pocked on the rear allows stored valuables to stay out of your way.

Shoes: On The Roger Pro 2 ($200)

Swiatek was previously sponsored by Asics. When she came over to On, she continued to wear an Asics model because her foot didn’t jibe with the original Roger Pro. However, she’s now sporting the second edition of the shoe. It boasts a fairly wide cut and lower arch profile. A carbon fiber Speedboard in the midsole provides stability and energy return into the next step. To boost durability, the mesh on the upper is now lighter, with more abrasion-resistant material, the top cap is reinforced to protect against foot dragging, and a TPU clip and upper overlays give additional structure and support. The outsole has also be revamped with an open herringbone pattern for a better combination of grip and give. There’s also a clay-court version with a tighter tread to help Swiatek perform long, controlled slides at Roland Garros.
