U.S. Polo Assn. Cotton Stretch Bikini Underwear vs Jockey Phantom Fit Bikini Briefs

Buy the U.S. Polo Assn. six-pack if you want everyday cotton stretch bikinis with a front pouch and a low-rise cut, and you value a large track record of owner ratings. Buy the Jockey Phantom Fit if you want the lightest, smoothest feel under clothes and a no-fly, second-skin fit. The Polo is cotton-blend, so it breathes and holds up to repeated washing; the Jockey is mostly polyamide and elastane, so it is silkier, stretches more and dries faster but can feel clingy. Owners rate both 4.6, though the Polo has far more ratings; Jockey buyers praise softness and complain about loose, inconsistent fit.

• Choose the U.S. Polo Assn. if you want a low-rise cotton stretch bikini with a front pouch, sold in a multi-pair pack for everyday rotation.
• Choose the Jockey Phantom Fit if you want an ultra-light, no-fly bikini that disappears under slim clothes and stretches with movement.
