When you toss the Carve Designs Women's Sanitas Reversible Bikini Bottom in your pack for a week-long surfing and beach camping trip in southern California, it's like you're packing two pairs in one. Featuring poppy prints on one side and a coordinating solid color on the other, these medium-cut bottoms offer 50+ UPF protection from the sun while you spend long days in the water. Four-way stretch, double-lined tricot stays put during sand volleyball and excursions off the shore.
