The PrimeMan Bikini Brief is Obviously's most minimal cut — a fitted, low-slung style with fabric-free leg openings, built for guys who want maximum coverage where it counts and none where it doesn't. 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 snug, fabric-free leg opening and a low-rise waistband that sits on the hips rather than the natural waist — the pick for guys who want a minimal, athletic silhouette under fitted clothing or for active wear. Available in sizes Small through X-Large in select colors.
