How to Choose a Competitive Swimsuit (Without Falling for Hype)

A practical guide to choosing the right racing suit or training suit: fit, compression, fabric, seams, approvals, and what actually matters on race day.

Start with the event and your goals

Not every swimmer needs (or benefits from) a top-tier race suit. Your event mix (50s vs 200+), how often you race, and how well you tolerate compression should drive the choice.

A simple rule: invest in comfort and repeatability first, then optimize performance details as your race schedule becomes more serious.

Fit and compression: tight is not the same as fast

Compression should feel supportive, not restrictive. If you can’t hit full range of motion in shoulders/hips, you’ll lose more from stroke degradation than you’ll gain from surface drag reduction.

Check for: smooth hip hinge, no pinching at the groin, no breathing restriction, and consistent tension (no loose pockets of fabric).

Fabric, seams, and construction details that matter

Look for fabrics that keep shape when wet and don’t ‘bag out’ after repeated pool sessions. For racing, bonded seams can reduce bulk and chafing, while for training, durability and chlorine resistance matter more.

Seam placement should support your kick and core alignment. A suit that forces an awkward posture is a suit that costs time.

Approvals and rules: know what your meet allows

If you compete in sanctioned events, confirm whether a suit needs to be approved by your federation (FINA/World Aquatics or local rules). Some meets restrict certain constructions.

When in doubt: prioritize compliant gear you can use confidently—no last-minute race-day surprises.

Care and lifespan

Racing suits are performance tools, not forever suits. Rinse immediately, avoid wringing, and dry in shade. For training suits, rotate pairs to extend life and maintain consistent feel in the water.

FAQ

Do tech suits always make you faster?
They can help by improving body position and reducing drag, but only if you can maintain your stroke mechanics. Poor fit or too much compression can slow you down.
How tight should a racing suit be?
Snug and supportive. You should feel compression, but you should still be able to achieve full range of motion and breathe normally.
