Calvin KleinBoy's Modern Cotton Assorted Briefs Underwear, Multipack Briefs

Q: Can these underwear be available for men?

Sure can. From my experience, an XL or 16-18 is roughly equivalent to a men's size small (28"-30" waist) and if you are smaller waist than that then maybe a size large would work for you. It depends upon the size your legs and butt etc so I suggest giving an XL a try and see what you think and go from there. There is one important thing to know about these and other larger sized boy's briefs: the pouch tends to be smaller and the legs a bit tighter than you might have experienced with comparable men's briefs. With that said, keep in mind that while these briefs are very stretchy and conform to the body, don't expect a large pouch like what you find on some other brands of men's briefs. I mean, they are sold as boy's briefs after all LOL. If you have worn men's CK briefs before (the more classic regular brief style) then you have already experienced a non-existent pouch and these boys briefs are really no different from those ones. Not sure why the other person to answer said such a flat out "no".... The way I see it is they are cheaper than similar men's CK briefs and they come in far better color choices so if you can fit into an XL or even a L size then why not? I say go for it.
