Calvin Klein Men's 3-Pack Bikini Brief with Tunnel Waistband
Review by Somebody : They're...ok

I've been trying to find a substitute for Undergear for years without success. I decided to try these under the impression they had a pouch design like UG Contour. They...kinda...have a suggestion of a pouch. Better than a lot but still not great. Maybe I got spoiled, or am just expecting too much, but I prefer the comfort and support of a pouch design brief. Don't get me wrong, these are comfortable for most of the day and seem well made. They fit right and don't ride up my butt. The tunnel waistband is a necessity....why do other brands seem to think I want raw elastic cutting into my waist all day?

Review by W. Finnegan : Comfort with looks

Excellent feel on the body to move with you and not bind. Love the comfort of the bikini and CK underware, very stylish and comfortable.

Review by Hui Lin : I love it

I like this simple design. And also the cotton quality is really good. Not tight and not loose, just the feeling that I am looking for.
