These compression shorts with the sport brief inside are ideal for a great workout or biking, etc. Whereas I would recommend the compression shorts with the jockstrap for MMA activities or other heavy workouts/boxing, the ones I bought with the brief are ideal for my everyday 3X week workouts. I feel more secure, safe, and my boys are safe and sound. Super product and I have more than one pair so I always have a clean one. -Customer Earl E.
