Briefs

Briefs provide the highest support with a close, secure fit and minimal fabric. Modern versions feature contoured pouches and breathable modal/mesh for better comfort than traditional "tighty-whities."

Boxer Briefs

The hybrid favorite: Supportive like briefs with mid-thigh coverage to prevent chafing. In 2026, they're enhanced with moisture-wicking fabrics and ergonomic pouches for all-day wear.

Trunks

A shorter, sleeker version of boxer briefs — perfect for a modern look under fitted clothing. They offer great ventilation and less bulk, ideal for warm NYC summers or slim pants.
