How Long Do Training Swimsuits Last? The Complete Guide for Active Women

Most active swimmers can expect a high-quality swimsuit to last 3–6 months with frequent pool use, and 6–12 months if they swim only a few times per week and follow a proper care routine. The exact lifespan depends on factors like fabric type, chlorine exposure, frequency of training and how well the suit is maintained.

As a general guide:

• 5–6x/week: 3–6 months
  
• 2–4x/week: 6–12 months
  
• 1x/week or less: 12–24 months
  

Cheaper swimsuits often lose shape within weeks, while durable fabrics like polyester/PBT or ECONYL® nylon blends retain elasticity and color much longer — making them ideal for regular training.

Which Factors Affect Swimsuit Lifespan the Most?

1. Chlorine Exposure

Chlorine is the number one factor that breaks down swimwear.
It weakens elastic fibres, fades colours, and causes fabric thinning.

This is why chlorine resistant swimsuits outperform traditional elastane-heavy suits.

2. Fabric Type: The Biggest Durability Indicator

Here is how different materials perform over time:

Jaze Swimwear uses ECONYL® because it combines durability, premium feel and sustainability — ideal for training-focused women.

3. Frequency of Use

The more often you swim, the faster your suit wears down.
Chlorine exposure + intense movement = natural fabric fatigue.

4. Fit and Stretch Retention

A suit loses performance once it:

• feels loose
  
• rides up
  
• loses compression
  
• absorbs water
  
• creates drag
  

Durable fabrics like ECONYL® or PBT blends maintain elasticity much longer.

5. Care Routine

Swimsuit care is one of the biggest lifespan boosters.
Correct care can double the longevity of your training suit.

How Can You Make Your Training Swimsuit Last Longer?

After every swim:

• Rinse the suit within 30 minutes in fresh, cold water
  
• Hand wash with mild soap only (no detergent!)
  
• Gently squeeze out water — no twisting or wringing
  

Drying:

• Lay flat or hang in the shade
  
• Never dry in direct sunlight
  
• Never use dryers, radiators or heated surfaces
  

Storage:

• Do not leave it damp in a bag
  
• Avoid rough surfaces that damage fibres
  

Bonus tip: Rotate swimsuits

Use two training swimsuits alternately to let the fibres recover.
This alone can extend lifespan by 50%.

When Should You Replace Your Training Swimsuit?

You know it's time to replace your suit when:

• Fabric becomes thin or shiny
  
• Colours fade dramatically
  
• The suit feels loose or unsupportive
  
• Straps stretch out
  
• Fabric starts sagging
  
• Bottom rides up
  
• It develops a chlorine smell that won’t wash out
  

If your suit no longer performs, it slows you down — and can affect your confidence in the water.
