7 Best Two-Piece Swimsuits for Training and Lap Swimming

Here’s a breakdown of the best two-piece swimsuits for women for swimming and training.

For swimmers lucky enough to train outdoors, a two-piece training swimsuit is essential. A two-piece suit maximizes skin exposure so that you can get more sunshine while also providing the same coverage and comfort of one-piece swimsuits.

But swimming laps outdoors isn’t as simple as throwing on your favorite bikini. You need a swimsuit that provides the same advantages as traditional one-piece training suits and takes it outdoors.

Fortunately, in recent years most of the major swim apparel companies have put out two-piece suits that can be used in the lap pool.

Key features that differentiate two-piece training swimsuits from bikinis:

• Drawstrings on the bottoms. One of the joys of swimming is going fast. Whether it is when you are diving in, pushing off, or doing sprints with swim training fins on, you will want drawstrings to keep your bottom secure.
• Hydrodynamic tops. Standard bikini tops often “catch” water. They are designed to show a little more chest and provide support, not necessarily be hydrodynamic. Two-piece tops are designed to let the water flow by.
• Two-piece swimsuits provide more coverage. This added coverage is to ensure that privacy is maintained while being active in the water.

While there aren’t as many two-piece training suits as there are one-piece swimsuits or bikinis, there are plenty of options, with a variety of cuts, backs, colors, and fabrics.

Here is our hand-picked selection of the best two-piece training swimsuits.
