Why You'll Love it

The suit that changed the perception of performance swimsuits.

  • Made in the best compressive swimwear fabric
  • Our innovative adjustable tie-back design allows for both a secure and comfy fit
  • Comes in 15+ colors
  • Superior tightly knit and compressive fabric that won't stretch out compared to lower-cost competitors

Details

One of our most classic and bestselling styles, the Jackson training one piece swimsuit is comfortable and stylish. The rounded neckline shape stays nice and flat when in streamline and the medium / full bum coverage keeps you covered while you're moving.

The Jackson's adjustable tie-straps give you the perfect fit for the moment—loose for comfort or snug for speed. 

Searchin' for a smaller size? Check out our 22J and 24J sizes! These suits offer a higher neckline and less fabric depth around the bum than our non-J sizes for a modest fit.

    As seen in

    We take design seriously.

    We take design seriously.

    1. Tie-back fastening system

    Our iconic tie-back lets you create your perfect fit. Loosen when you want to take it easy, tighten when you're ready for the fast lane.

    2. Double fold binding

    This super durable construction can withstand hours of stretching and pulling in very harsh elements like chlorine and sun.

    3. Reinforced stitching

    We use bar tacks at major stress points - the neck, back, and where hems start and stop to prevent unraveling.

    4. Chlorine-Proof

    Our signature Foreverever fabric won't breakdown and is highly fade resistant.
