More than a typical swimsuit, an athletic one piece swimsuit is made for - you guessed it - swimming, diving, surfing, paddleboarding, and just about any aquatic sport. Athletic one piece swimsuits are designed for women athletes making some serious moves in the water. You'll never have to adjust your suit or worry about anything popping out. Whatever water sport you're into, choosing the right swimsuit can make all the difference in how you move and how you feel. That's why we love athletic one-pieces. They give us a boost while we freestyle, stay put through every wave and wipeout, and provide better coverage than a two-piece swimsuit would. Of course, we can't talk about one-piece swimsuits without mentioning Australian swimmer Annette Kellerman: the woman who pioneered the athletic one-piece we all know today. She designed the first form-fitting one piece to be more aerodynamic to power her swim across the English Channel (she was the first woman to ever attempt this - a total badass). The one-piece, known at the time as the 'Annette Kellermann,' changed women's swimwear forever.
