Size Guide

Torso measurement is most important for finding your accurate one piece size.

If you are in between torso measurements or know your torso runs long we recommend sizing up!

Details

One of our most classic styles, the Jackson training one piece swimsuit is better than ever with our fourth design update. (Hey - we never stop listening to your feedback on making the best suits we can!)

This version is raised over the apex, aka, more length coverage for your torso. The more rounded neckline shape stays even flatter when in streamline and a single binding loop adds a minimalist finish we love. 

As always, the Jackson provides medium/full bum coverage and the adjustable tie-straps give you the perfect fit for the moment—loose for comfort or snug for speed. 

 Features:

  • Good for: Swimming, water polo, lifeguarding, paddling, ocean and pool activities
  • Tie-Back one-piece swimsuit
  • Medium / Full Coverage
  • Coverage 4
  • Unpadded
  • Lined for maximum privacy
  • Tagless for maximum comfort
  • Chlorine proof
  • 2-way stretch
  • Reinforced stitching

Fabric Composition:

Care Instructions:

  • Hand wash cold
  • Hang dry
  • Do not iron, dry clean or bleach 

 JOLYN does not recommend tie straps to be used in racing or FINA sanctioned events. Fastening systems including ties are not allowed in competition, as per FINA regulations.
