"I bought these in Black a couple of years ago. They are as good today as when they were made and are very comfortable and good for distance swimming. They are perfect for the closet exhibitionist - the full seat and wide sides give ample coverage for beach and pool wear, the enhancing pouch does exactly what it says! This year I've bought them in light blue. These are even more daring as lighter colours can give the illusion of transparency - as I noticed on looking at a pic my wife took which shows off an "acorn" profile... I love them!"

"These are perfect, the material is cut right at the top of the leg so doesn't move while swimming, and the pouch keeps everything comfortably in place. Enough coverage for the local Leisure centre and a nice choice of colours."

"The X4D design does exactly as it says. The fabric presses gently on the underside of your scrotum lifting your tackle and pushes it up and forward to completely fill out the perfectly shaped pouch. This bikini is not for the bashful, as it gives you a very prominent bulge, with everything proudly on display . I love the profile they create, which appeals to my exhibitionist side. I could wear them all day as they are really comfortable, the fabric is silky smooth and appears high quality. They are also low cut with very narrow sides which I prefer. My partner loves me in them too, which is a real bonus. I’ll definitely be wearing them with him to the beach this weekend."

"Great swim brief for swimming laps at local sports centre, secure with tie cord on the waist. The pouch is very comfortable and not too much of a bulge."
