I can’t verify the 2026 Kona Marathon shirt design from the information available here, so I can’t describe it confidently without guessing. The only official race page I found says participants receive an official T-shirt, but it does not show the 2026 shirt design.

What’s confirmed

  • The Kona Marathon registration page includes an official participant T-shirt as part of entry.
  • I did not find a reliable public image or product page showing the 2026 shirt itself in the available results.

Closest related clue

  • There are public Kona apparel listings and team gear pages, but they appear to be general merchandise rather than the 2026 marathon participant shirt.
  • Because of that, any visual description of the 2026 shirt would be speculation, not a verified answer.

Best next step

If you want the exact look, the most likely sources are the race’s registration materials, packet pickup details, or official event announcements for 2026.
