Flat Rib Marine Bikini Bottom - Women's

What Our Gearhead® Experts Are Saying:

"I recommend this bottom for anyone who wants more coverage without sacrificing style. The high-rise fit feels secure during swims, and the waistband stays comfortable whether I’m lounging or moving around. It’s snug when dry but settles in perfectly once you’re in the water."

For long afternoons by the water and spontaneous swims under the sun, the Flat Rib Marine Bikini Bottom from Nani Swimwear brings together comfort and confidence. Designed with a flattering high-rise cut, it offers the coverage we want without limiting movement or style.

The supportive waistband smooths and stays in place through beach walks, paddle sessions, and poolside lounging. Crafted from a recycled polyamide stretch blend with a soft lining, it feels secure when dry and remains comfortable once wet. With full coverage and UPF 50 sun protection built in, this bottom is ready for everything from active swim days to relaxed coastal escapes.
