Calvin Klein Underwear's Delta bikini bottom is from the label's INTENSE POWER collection, where matte and glossy designs go hand in hand and are ultimately rounded out by striking logo details. Such is the case with these bikini bottoms, whose back hem is set off by contrasting CK lettering. At the front, however, the label has eschewed the typical branding in favor of an elegant V-cut - and it sets you off beautifully in the pool and on the beach. And best of all, the pants are made largely from recycled material.
