Description

The PrimeMan Brief is Obviously's full-coverage classic — a deep seat and wide leg openings built for guys with larger or more muscular legs who want support without any pinching.

The AnatoMax pouch

Every PrimeMan style is built around the AnatoMax anatomical pouch — a three-dimensional shape that keeps things naturally separated and supported instead of pressed flat against your body. Less friction, less heat, and no reaching in to readjust halfway through the day.

Fabric & construction

Cut from an ultra-soft MicroModal and Lycra blend with four-way stretch — breathable, moisture-wicking, and noticeably lighter than cotton. The premium soft-back logo waistband sits flat without pinching, and the care label is printed directly onto the fabric, so there's no tag scratching your skin.

The fit

A deep seat with more room in the buttocks and wider leg openings than our slimmer cuts — built to move naturally with your body rather than fight it. Available in sizes Small through XXX-Large in select colors.
