For the coming spring and summer season, Swiss sportswear brand ON has continued to develop its men’s tennis apparel offering with updates to established Court and Courtside styles. This new collection focuses on lightweight construction, warm-weather performance and subtle seasonal design changes rather than introducing entirely new silhouettes.
A notable visual update for the season is the introduction of Fade colors for some of the core pieces.

On-Court Performance Apparel
The foundation of the collection remains On’s Court line, designed for match play and training.
Court-T and Court Tank
The Court-T and Court Tank continue as the primary performance tops for the coming warm seasons. Both are constructed from lightweight, breathable fabrics intended to support heat management and unrestricted movement during play. For this season, selected versions are offered in Fade colorways, featuring subtle gradient transitions that add visual interest while maintaining a clean, understated look.

Court Short (5″ and 7″)
The Court Short is again available in both 5″ and 7″ inseam lengths. These shorts are built with stretch materials and an adjustable waistband to support lateral movement and quick changes of direction. Fade versions are also introduced in select styles, aligning the shorts visually with the updated tops.

Courtside and Warm-Up Pieces
In addition to match-ready apparel, the collection includes Courtside pieces designed for warm-ups, practice and off-court use.
Courtside-T and Courtside Polo
These styles are made from softer, premium-feel fabrics and are intended for lower-intensity activity or casual wear.
Courtside Jacket and Courtside Pants
Lightweight jackets and pants remain part of the Courtside range, offering streamlined warm-up options suitable for pre-match routines, travel and recovery.

Materials and Sustainability
Sustainability continues to be a consistent focus across ON’s apparel lines. Many pieces in the Spring/Summer 2026 tennis collection incorporate recycled polyester and responsibly sourced materials.
Design and Fit
The overall design approach for spring and summer -26 remains restrained and functional:
- Neutral base colors with seasonal Fade gradient options
- Minimal, unobtrusive On branding
- Modern athletic fits that balance clean lines with freedom of movement
Summary – ON’s 2026 collections for men
These new pieces builds on existing Court and Courtside silhouettes with incremental updates rather than major redesigns. The introduction of Fade colorways across select Court-T, Court Tank and Court Short styles stands out as the key seasonal change, adding a refined visual update while maintaining the collection’s performance-focused, minimalist identity.
