This New Custom AI Kit Will Fit You Perfectly–And a One-Off Custom Design Isn’t As Much as You Think 

April 29, 2026

Regna, a new Singapore-based triathlon kit brand, uses AI via its PHOTOtoFIT app to scan users’ bodies from two photos, capturing 100 precise measurements for individually custom-cut and printed trisuits, cycling kits, and running apparel, making perfect fits accessible without high costs or minimum orders.

Priced at $475—competitive with premium brands like Castelli ($450) or Surpass ($755)—the process starts with basic profile info and optional design mock-ups, followed by AI scanning in tight clothing (needing a helper for photos), leading to quick designer refinements and delivery in about two weeks for custom cuts or slightly longer for prints.

The study found the product, built with high-quality Italian/Swiss fabrics for cooling, compression, aerodynamics, UV protection, and quick-dry properties, the trisuit fit exceptionally well during a hot race at Challenge Gran Canaria, staying comfortable without chafing, holding ample fuel securely, though minor gripper and seam issues were noted. Overall, Regna delivers pro-level custom performance gear simply and affordably, impressing with fit and function despite calls for more wind-tunnel data. Slowswitch
