For competitive swimmers, a training suit is not just apparel—it is daily equipment. Yet many swimmers continue using worn-out suits far longer than they should, often without realizing the impact on comfort, performance, and durability.
So how often should a competitive swimmer actually replace their training suit? The answer depends on training volume, fabric type, and how the suit is cared for.
The Short Answer
Most competitive swimmers should replace their primary training suit every 3 to 6 months.
For high-volume swimmers training 5–9 times per week, closer to 3 months is common. For lower-volume or masters swimmers, a suit may last closer to 6 months or slightly longer.
Why Training Suits Wear Out Faster Than You Think
Chlorine is extremely aggressive on swimwear. Every practice exposes fabric to chemicals that break down elasticity, weaken fibers, and reduce compression.
Even durable polyester suits are not immune—they are simply more resistant.
Over time, this leads to:
- Loss of compression and support
- Fabric thinning and transparency
- Loose straps and poor body position
- Increased drag in the water
Clear Signs It’s Time to Replace Your Training Suit
If you notice any of the following, your suit is no longer doing its job:
- The suit feels noticeably looser, even when dry
- Straps stretch easily or shift during swimming
- Fabric looks faded, shiny, or thin in high-friction areas
- The suit absorbs water and feels heavy mid-practice
- You constantly need to adjust it while swimming
A training suit should feel secure, supportive, and predictable. Once that consistency is gone, performance is affected—even if subtly.
Training Volume Matters
How often you train is one of the biggest factors in suit lifespan:
- 8–9 sessions per week: Replace every ~3 months
- 5–6 sessions per week: Replace every 4–5 months
- 3–4 sessions per week: Replace every 5–6 months
Swimmers training twice a day should expect faster wear, especially around seams and straps.
Fabric Choice Makes a Difference
Not all training suits are built the same.
100% polyester suits are the best option for daily training. They retain shape longer, resist chlorine damage, and maintain fit over time.
Suits made with blended fabrics (such as nylon or elastane blends) may feel softer initially but tend to lose compression much faster under heavy use.
For competitive swimmers, durability and consistency matter far more than short-term comfort.
How to Extend the Life of Your Training Suit
While no suit lasts forever, proper care can significantly slow wear:
- Rinse immediately in cold water after every swim
- Never wring or twist the fabric
- Air dry only—avoid dryers and direct heat
- Rotate between two training suits if possible
- Never store a wet suit in a closed bag
Rotating suits alone can add weeks—or even months—to their usable lifespan.
Why Replacing Your Suit Matters More Than You Think
A worn training suit increases drag, reduces body awareness, and changes how water flows around you. Over time, swimmers unconsciously adjust their stroke to compensate.
Training consistently in a suit that fits correctly supports better habits, better feel for the water, and more reliable performance.
Replacing your training suit on time is not about looking new—it is about training correctly.
Final Thoughts
If you train hard, your suit works hard. Expecting one training suit to last an entire season is unrealistic for most competitive swimmers.
Pay attention to fit, feel, and function. When those start to slip, it’s time to replace your suit and keep your training environment as consistent as possible.
