First Serve Stripe S

First Serve Stripe

First Serve Stripe feels like standing behind the baseline before the ball even goes up. Outside, it can still be a commute, a flight, errands, or a weekend date; underneath, the first serve is already clean, steady, and ready.

The blue-green lines and pale ground carry the feeling of court markings, net rhythm, and a little club-uniform sharpness. It is not the loud racket-all-over pair. It feels more like warm-up minutes before the match: breathe, find the grip, serve first.

Wear it for hot days, travel, weekends, or as an easy first step from solids into prints. The MicroModal™ Boxer gives relaxed coverage and a soft feel, making this first serve ready for home, travel, and after-court downtime.

Reinvented Comfort: Premium Jersey Cotton

T-Shirt Softness: High-end jersey knit that is soft, breathable, and never stiff.
4-Way Stretch: Moves with you during sleep for total, zero-restriction comfort.
Heat Regulation: A high-airflow weave actively prevents overheating.
Cool Touch: Engineered to keep you refreshed during lounging or sleep.

Irritation-Free: Fabric-Encased Waistband

Designed for sensitive skin, our waistband is fully wrapped in ultra-soft self-fabric. With no exposed elastic touching your body, it provides a secure, gentle hold that leaves zero skin marks and ensures all-day (and all-night) comfort.

Total Mobility: Flexible Leg Openings

Experience true "Free Breathing" with a precision-cut loose fit through the thigh. Engineered for maximum airflow and freedom of movement, these leg openings provide an airy, unrestrictive silhouette that stays comfortable in any position.

Refined Detail: Premium Pearl-Button Fly

Finished with a lustrous pearlescent button and reinforced stitching, our functional fly combines security with sophisticated style. The reinforced closure ensures a worry-free fit that stays closed when you need it while adding a touch of artisan luxury.
