CONS: Fly opening way to small. The size runs a little big. Don't fit as snug as regular boxer briefs. PROS: The only reason for a 4 was the fly have to pull out the bat out through the opening at bottom of the pouch, other than that their are great. But would like to see the pouches a little larger . I have a 32 waist and small frame body, but the Medium is a little large, and almost fit like boxers. As to the 2 pouches their are ok but need more room in the pouch but still very nice, Iam a little on the hung side. Would like to try on a small, but won;t pay the price to if they fit better. Would love them to send me a small pair for a trial run, want to buy more. The first day I gave them a workout, landscaping at 80 degrees out. The bat and balls stayed in place and very pleasant feeling, stayed dry. I can say they make you look more hung then you are and wearing basketball shorts it does show the outline of your area with a bulge. Don't recommend wearing to bed unless you take the bat out of the pouch and just let it hang out the bottom of it. Mother nature want it to straighten out natural and the pouch is forcing it down.
