Calvin Klein Modern Cotton Stretch Bikini Brief vs U.S. Polo Assn. Cotton Stretch Bikini Underwear

These are not really rivals: the Calvin Klein Modern Cotton Stretch Bikini is a women's single brief in a modal-cotton blend, while the U.S. Polo Assn. six-pack is men's low-rise cotton stretch bikini underwear. Buy the Calvin Klein for one well-made women's brief in a soft modal blend; buy the U.S. Polo Assn. pack if you want several men's briefs in one go. The Calvin Klein has the better fabric feel and brand cachet; the U.S. Polo Assn. wins on value per pair and has a large, well-rated owner base.

• Choose the Calvin Klein if you are a woman who wants one soft modal-blend bikini brief in a solid color and prefer a known designer label.
• Choose the U.S. Polo Assn. if you are a man who wants several low-rise cotton stretch bikini briefs in one pack at a low cost per pair.
