Does Triumph Japan run small or big?

1Band

Triumph Japan bands run true to size across EU bands 65–90: start with your measured band on the loosest hook, and expect it to feel snug for the first week if you are coming from an add-inches size.

2Cup

Triumph Japan cups grade small from A to H: try your measured cup and one up, and read a floating gore as the cup, not the band.

3Wire & straps

Triumph Japan wires run narrow: good for projected, narrow-root shapes; wide roots may find them digging at the side. Straps: Fine.
