Flow Shift

Comfortable Men's Underwear with Ultralight, Quick-Dry Performance and Joey Pouch® Support

Men's performance underwear should stay light, dry, and comfortable when the pace picks up. Flow Shift combines an ultralight polyester-modal blend, all-over perforation, quick-dry performance, and the patented Joey Pouch® for support through medium to high-intensity sport and everyday activity.

Choose the fit that works for your day. Flow Shift comes in a 3 inch trunk, 6 inch boxer brief, and 9 inch long leg, with single pairs and three-packs available across the collection. The lightweight perforated construction is designed for airflow and faster drying whether you are training, competing, or moving through an active day.

For a softer everyday option, Swing Shift brings premium modal comfort to the daily rotation. Prefer bamboo-blend casual comfort? Shop Day Shift. For another active option made for intensity training and sport, compare Sport Shift. When the forecast calls for more coverage, Long John is built for layering.

Flow Shift is the move when lightweight and quick-drying matter. The Joey Pouch® keeps support handled while the perforated fabric does the breathing. Pick your inseam, get moving, and let your underwear keep up without becoming part of the workout.
