Brand JUSTIN+SIMON
Discover JUSTIN+SIMON—men’s underwear designed to blend confident style with all-day comfort. This collection brings together sleek bikinis, classic briefs, athletic trunks, modern boxer briefs, and open-back jockstraps, each cut to support your routine from early workouts to late nights out. If you want clean lines, breathable fabrics, and construction that actually keeps up, you are in the right place.
Comfort starts with materials. JUSTIN+SIMON uses smooth microfibers, silky modal blends, and cotton-rich knits chosen for airflow and a soft hand feel. Four-way stretch moves with you without sagging, while moisture-managing fibers help you stay fresh through commutes, training sessions, travel days, and long events. Flat seams and tag less interiors reduce friction, and flexible waist elastics lie clean under denim, chinos, or performance layers so your profile looks sharp on and off camera.
Fit is the difference you feel. Ergonomic pouch shaping offers natural lift and support without squeeze, keeping everything secure during movement. Many styles include inclusive sizing with deeper rises and room where it counts, making it easier to dial a confident fit across body types. Use our size guide to confirm measurements, then build a small rotation in your favorite cut to keep fit consistent across colors and prints.
Design is where JUSTIN+SIMON stands out. Expect refined color stories—from essential neutrals to statement bright—plus mesh panels for targeted airflow, contour stitching for structure, and waistbands that hold their snap wash after wash. Minimal bikinis create a sleek, low-rise profile under tailored looks. Contour-pouch briefs stabilize for active days. Trunks and boxer briefs bring modern coverage with an athletic vibe. Jockstraps deliver open-back freedom and a sharp, confident silhouette when you want maximum mobility.
Building your drawer is simple:
-
Start with two everyday neutrals (briefs or trunks) for work and travel.
-
Add one bold or mesh style for nights out, shoots, or special events.
-
Round it off with a multipack of your go-to cut to lock value per pair and keep a fresh option ready.
Traveling or on the go. Quick-dry blends rinse easily and rebound fast, making them ideal for gym-to-dinner schedules or weekend trips. Pack two or three favorites, rotate as you move, and keep comfort high from first flight to last event. If you perform, stream, or model, duplicating a preferred style keeps your on-camera fit consistent under lights and long sets.

Qualifying US orders ship discreetly for free, while affordable priority options keep smaller carts moving quickly. Need help choosing a fabric, cut, or size.

Quality you can feel defines this brand: resilient elastic that holds shape, precise stitching, smooth bindings that lie flat, and colors that stay true after repeated wear.
