1. Onia Sienna Swimsuit ($150)

A year ago, the one-strap was a trend; now it's entering staple territory. Onia's nylon-spandex suit creates a flattering silhouette with its two-tone color blocking and cutout back. Available in five colorways. Buy it at Amazon.

2. Moscot Originals Lemtosh Sunglasses ($290)

"Transparent frames have never looked ­better," said Justin Fenner at Men's Journal — thanks to brands going see-through on classic eyeglass shapes. You've probably seen Truman Capote and Jeff Goldblum in the Lemtosh, and the frame looks great with bottle-green lenses. Buy it at Moscot.

3. Yeti Tundra 35 Cooler ($250)

Yeti coolers are the best around, combining outstanding performance with "a fabulous sense of style", said Sunset. This summer, the Tundra 35, which holds 21 cans plus ice, is one of three sizes available in a limited-edition coral hue. Buy it at Amazon.

4. Badger Sport Broad Spectrum Sunscreen ($16)

More and more beachgoers are realizing that the chemicals in standard sunscreens are devastating the world's coral reefs. Avoid oxybenzone and octinoxate and choose one with zinc oxide instead, such as this unscented, organic, water-resistant cream. Buy it at Amazon.

5. Color Wheel Towel by Ban.do ($68)

We could tell you round beach towels have taken off because they're roomy enough for two, "but mostly they're fun and charming." Ban.do is a good source, especially if you like watermelon cross-sections and other loud patterns. Buy it at Amazon.
