You train. You paddle. You surf. And at some point, your swimsuit gives up before you do.


Fabric thins. Straps stretch. Coverage shifts mid-session. Different water places different demands on your suit. If you move between pool and ocean, you already know this. Here’s what actually holds up — and what doesn’t.

Lap Swimming: The Hardest Thing You Can Do to a Swimsuit

Pool training is repetitive impact. Chlorine. Compression under force. Most fashion swimwear lasts 20–30 sessions. Then it stretches. A training suit must survive 100+.


Hundreds of identical arm movements. Flip turns slamming fabric against your body. Chlorine exposure three to five times a week. Pool swimming destroys swimwear faster than any other water activity.


What matters:

  • Compression fit that creates zero drag
  • Chlorine-resistant fabric that won't degrade after 50 sessions
  • Racerback or cross-back construction that completely frees the shoulders
  • Built-in shelf bra (underwire and pool walls don't get along)

Here's what people consistently get wrong: the suit should feel snug when dry. Almost compressive. Water adds slack to everything, so a suit that feels "comfortable" on land will feel loose in the pool.


Loose means drag. Drag means slower splits.


Our Liberty Racerback swimsuits are built for exactly this—athletic construction that holds compression through extended sessions without restricting your stroke.


When your suit disappears from your awareness, your focus shifts to pace — not adjustment.

“After 3 months of 4x/week training, it still fits like day one.”

Open Water Swimming: Temperature, Visibility, Layering

Open water is exposure.Temperature. Current. Sun. Distance from shore. Safety is not aesthetic. It is structural.


The ocean is not the pool. You're dealing with temperature fluctuation, current, waves, and how visible you are to boats, kayakers, and safety crews.


Bright colours increase visibility in open water by up to 5x compared to dark tones. Boats see you earlier. Safety crews see you faster.


What matters:

  • Bright colours (safety consideration, not fashion choice)
  • Full back coverage for warmth and sun protection
  • Secure closures that won't fail when waves hit
  • Ability to layer under a springsuit when water drops below 18°C

Wearing a pool suit in the ocean and wondering why you're freezing after twenty minutes is like wearing trainers to hike a mountain. Technically footwear. Functionally wrong.


Our Yemaya one-piece swimsuits provide the coverage and construction that open water demands—and they're designed to work as a base layer when you need thermal protection.


The right suit lets you stay longer — because you’re not fighting cold or fabric.

Surfing: Wipeout-Proof First, Everything Else Second

The cost of the wrong suit in the surf is not an inconvenience. It’s exposure mid-wipeout.


Surfing needs suits that survive wipeouts. That's the starting point. Pop-up range of motion, quick drying, board-compatible construction—all of that matters, but if the suit shifts position on your first duck dive, none of it counts.


What matters:

  • No ties, clasps, or hardware that catches on boards or leashes
  • Bonded seams that handle high-force impacts
  • Performance rubber (regular fashion swimwear cannot handle surfing forces)
  • Secure fit that doesn't move during extended sessions

Our Horizonia Yulex springsuits are built for exactly this—85% plant-based natural rubber with bonded construction that stays in place through whatever the ocean throws at you.


No ties. No shifting. No second thoughts.

Paddleboarding: The One That Sneaks Up on People

Kneeling, standing, reaching, falling in, and the whole time sitting in direct sun. UV damage is cumulative, and UV reflected off water makes exposure significantly worse than you'd expect.


What matters:

  • UPF 50+ fabric (non-negotiable)
  • Sleeveless or short-sleeve cuts for coverage-to-ventilation balance
  • Works alone in warm weather, as a base layer when it gets cooler
  • Stays in place across kneeling, standing, and paddle stroke positions

This is where versatile construction earns its value. A suit that handles paddleboarding should also handle the transition to a wetsuit layer without bunching or shifting.

Multi-Activity: What Versatility Actually Looks Like

If you train midweek and enter the ocean on weekends, you don’t need more swimwear.
You need smarter swimwear.

Most women who spend real time around water don't do one thing. They're in the pool on Wednesday, the ocean on Saturday, and on the paddleboard Sunday.


Versatility is not doing everything acceptably. It’s performing where you actually live.


What a true multi-activity suit needs:

  • Durable fabric that doesn't degrade from chlorine-to-saltwater cycling
  • UV protection built into the fabric, not added as a coating
  • A fit that holds across different movement patterns
  • Construction that performs in both compression (pool) and coverage (ocean) scenarios

This is what versatility actually means when you live between the pool and the ocean. Not a suit that does everything acceptably. A suit that does the things you actually do well.

The Bottom Line

Spring training season starts now.
If you’re increasing water time, your suit should increase with you.


The right suit removes friction. The wrong one creates it. Choose what holds up.


A racerback swimsuit for pool training. A full-coverage one-piece for open water and paddleboarding. A springsuit for when temperatures drop. A changing robe for transitions between sessions.


Generic guides won't tell you this because generic guides aren't written by people who actually train in water five days a week.


We are.

Different Water, Different Demands

What your swimwear actually needs to handle

Generic guides talk about necklines. We talk about what survives 400m repeats versus a 2-hour paddle session.

LAP SWIMMING

The hardest thing you can do to a swimsuit

Compression Fit Chlorine Resistant Racerback Cut Low Drag

Pro tip: Should feel snug when dry. Water adds slack - comfortable on land means loose in the pool.

OPEN WATER SWIMMING

Temperature, visibility, layering capability

Bright Colours Full Back Coverage Secure Closures Wetsuit Compatible

Pro tip: Bright colours are not fashion - they are safety. Must layer under a springsuit below 18C.

SURFING

Wipeout-proof first, everything else second

No Hardware Bonded Seams Performance Neoprene Stay-Put Fit

Pro tip: If it shifts on your first duck dive, nothing else matters. No ties, clasps, or catches.

PADDLEBOARDING

The one that sneaks up on people

UPF 50+ Required Sleeveless/Short Sleeve Base Layer Ready Multi-Position Fit

Pro tip: UV reflected off water doubles exposure. UPF 50+ is not optional - it is essential.

MULTI-ACTIVITY

Pool Wednesday, ocean Saturday, paddleboard Sunday

Chlorine + Salt Resistant Built-In UV Protection Holds Across Movements Durable Construction

Pro tip: True versatility = performs well at what you actually do, not acceptably at everything.
