Finis HydroX jammer

Amplify your confidence in the HydroX - our latest innovation in competition swimwear. We perfected the most essential details of the race suit, starting with the fabric and the way it interacts with muscle. The threads of our proprietary MemoryFlex® fabric are positioned to optimize the natural expansion and contraction of the muscle, providing consistent compression for the highest performance. MemoryFlex® is a smart material that will return to its original shape throughout the stroke cycle, enhancing flexibility and compression. Simply the best, FINIS HydroX.

Fit Tips:

Use the Measurement Guide First:
- We won’t sugarcoat it — measuring takes a little time (just like putting on a tech suit). Use our Measurement Guide so you can be as confident in your sizing as you are on race day.

The Right Fit May Feel Surprising:
- HydroX is designed to go on more easily than traditional tech suits. Especially for female swimmers, it may feel “too easy” to put on at first—this is intentional. If the suit fits smoothly and comfortably, you’re likely in the correct size.

Balanced Compression & Mobility:
- The suit should feel like a second skin—supportive without feeling overly restrictive. You should be able to move freely, including bending into a start position, without discomfort.

Care Instructions:

- Rinse immediately after use with cool, non-chlorinated water.
- Do not machine wash or use any type of soap/fabric softener.
- Lay flat to dry; do not use any type of dyer.
- Store in a cool, dry environment.
