In between brief and square-cut

[JamesSwim]

What does one call a swim suit that's larger than a competition style brief and smaller than a square cut? I am beginning to see more of these, such as at H&M retail store (but not on their web site).

Some companies give it their own brand name such as the Corcovado brief linked below, others calls it a trunk. But a trunk can refer to many styles.
